Graph of
Similarly,
x | -2 | -1 | 0 | 1 | 2 | 3 |
y | -2 | 0 | 2 | 4 | 2 | 0 |
Conclusion:
It is a modulus function.
(b)
Vertex of the graph.

Answer to Problem 2CB
vertex of the graph is (1,4)
Explanation of Solution
Given data:
Graph of the equation
Calculation:
The vertex of the graph is the point from where the line of graph changes its direction.
So the vertex of the graph is (1,4)
Conclusion:
vertex of the graph is (1,4)
(c)
Domain and range of the function.

Answer to Problem 2CB
The domain is
Explanation of Solution
Given data:
Graph of the equation
Calculation:
By the graph it can be seen that the value of x for the equation is all real number
So the domain is
And the value of y axis is from 4 to -8
So the range is
Conclusion:
The domain is

Answer to Problem 2CB
The y-intercept is 2 and the x-intercept is 3.
Explanation of Solution
Given data:
Calculation:
The y intercept of the
And the x-intercept of the
Conclusion:
The y-intercept is 2 and the x-intercept is 3.
(e)
The range of function by vertex and sign of a.
(e)
Answer to Problem 2CB
As the vertex is the point from where direction of line change so it will tell us about the highest or lowest value of range of function.and the sign of a will tell about the direction of line coming from so it will tell us the highest value of range.
Explanation of Solution
Given data:
As the vertex is the point from where direction of line change so it will tell us about the highest or lowest value of range of function.and the sign of a will tell about the direction of line coming from so it will tell us the highest value of range.
Conclusion:
As the vertex is the point from where direction of line change so it will tell us about the highest or lowest value of range of function.and the sign of a will tell about the direction of line coming from so it will tell us the highest value of range.

- Thank you.arrow_forwardThank you.arrow_forwardLet V, W, and Y be vector spaces. Suppose dim(V) dim(W) = dim(Y) = 2. = Let ("beta") be an ordered basis for V. Let ("gamma") be an ordered basis for W. Let ("zeta") be an ordered basis for Y. Suppose S is a linear transformation from V to W and that T is a linear trans- formation from W to Y. Remember that ToS is the function from V to Y defined by (TOS)(v) = T(S(v)). (a) Prove that To S is a linear transformation. (b) Prove that ° [T • S] = [T]{[S]}.arrow_forward
- Let W={(0, a, 0) | a Є R}. (a) List four elements from W. (b) Determine whether W is a subspace of R³, and prove that your answer is correct.arrow_forwardFor this problem, refer to the network as shown in Figure 1, answer the following questions. B A C FIGURE 1. For Problem (7). Let x₁ be the number of users at website A. Let x2 be the number of users at website B. Let x3 be the number of users at website C. Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then... (b) Use elementary row operations to put the augmented matrix into reduced row echelon form, and then... (c) Write down the solution space for this system of equations, and then... (d) Identify which website(s) would be ranked most highly by PageRank.arrow_forward4 2 Let C = -6 -3 (a) Find det(C). (b) Use your answer for (a) to determine whether C is invertible.arrow_forward
