(a)
To find: The slope and y-intercept of linear function
(a)

Answer to Problem 4RE
Slope
y-intercept
Explanation of Solution
Given:
Slope: The coefficient of x of linear function.
Slope
y-intercept: The constant part of the function.
y-intercept
(b)
To find:Theaverage rate of change of function
(b)

Answer to Problem 4RE
Explanation of Solution
Given:
The average rate of change of linear function is constant. Average rate is change in y over change in x.
In another way, It would be slope of linear function.
Therefore, the average rate is
(c)
To graph: Thelinear function
(c)

Answer to Problem 4RE
Explanation of Solution
Given:
The given linear function,
First make the table of x and y. By taking some random value of x
Now plot the points on graph.
(d)
To find: The increasing, decreasing or constant of function
(d)

Answer to Problem 4RE
decreasing
Explanation of Solution
Given:
The average rate of change of linear function is constant. Average rate is change in y over change in x.
In another way, It would be slope of linear function.
The rate of the function is negative. If the rate of linear function is negative then it would be decreasing function.

- Let the region R be the area enclosed by the function f(x)= = 3x² and g(x) = 4x. If the region R is the base of a solid such that each cross section perpendicular to the x-axis is an isosceles right triangle with a leg in the region R, find the volume of the solid.
