Revolt · Accepted Answer

44

Question 2

Which represents the inverse of the function f(x) = 4x?

Revolt · Accepted Answer

h(x) = x

Question 3

What is the inverse of the function f(x) = 2x + 1?

Revolt · Accepted Answer

h(x) = x –

Question 4

What is the inverse of the function f(x) = 2x – 10?

Revolt · Accepted Answer

h(x) = x + 5

If f(x) = + 8, what is f(x) when x = 10?

Revolt · Accepted Answer

13

Question 6

On a coordinate plane, a straight red line with a negative slope, labeled g of x, crosses the y-axis at (0, negative 7). A straight blue line with a positive slope, labeled f of x, crosses the x-axis at (negative 1, 0) and the y-axis at (0, 2). Both lines intersect at (negative 3, negative 4).

Revolt · Accepted Answer

f(–3) = g(–3)

Question 7

Two functions are graphed on the coordinate plane.

Revolt · Accepted Answer

f(–4) = g(–4) and f(0) = g(0)

Question 8

On a coordinate plane, a straight red line with a positive slope, labeled g of x, crosses the x-axis at (negative 3, 0) and the y-axis at (0, 3). A straight blue line with a positive slope, labeled f of x, crosses the y-axis at (0, negative 3) and the x-axis at (1, 0). Both lines intersect at (3, 6).

Revolt · Accepted Answer

f(3) = g(3)

Question 9

What is the inverse of the function f(x) = x + 2?

Revolt · Accepted Answer

h(x) = 9x – 18

Question 10
