X-4 f(x) = х-5

Q: F(X) = -X4  + X2 +3 How to solve for x?

A: Given,

Q: f(x)=√x-2 if x>-1; f(-2) 1-(x-2) ifx ≤-1

A: To find f(-2) , substitute x= -2 in the corresponding function.

Q: f(x) = x + 5, g(x) = x - 4 Find (f + g)(-4).

A:

Q: h(x) = x2 + x + 4

A: The function h is defined as

Q: f(x)=x2-5x-4 f(x+a)= ?

A:

Q: if h(x)=x2-6, find h-1(x)

A: To find the inverse of the function, use the below steps. Replace h(x) by y, so we get y = x2 - 6

Q: S(x)= 2-1 x* +X Simplify

A:

Q: f(x) -5 -5 5 2.

A: To find the x-intercepts of the polynomial function. f(x) = (x + 1)(2x - 6)(x - 5)f(x) = x3 - 4x2…

Q: f(x)=2x-5 What is -f(a)

A: Here I am attaching image so that you understand each and every step.

Q: (x+2)(y-2)=(x-9)(y+5)

A: Open the bracket, we getxy - 2x + 2y -4 = xy +5x - 9y -45

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
