Which statement is true regarding the graphed functions?
A
f(4) = g(4)B
f(4) = g(–2)C
f(2) = g(–2)D
f(–2) = g(–2)3
What is the inverse of the function f(x) = 2x + 1?
A
h(x) = x –B
h(x) = x +C
h(x) = x – 2D
h(x) = x + 24

The functions f(x) and g(x) are graphed.
A
f(0) = g(0) and f(2) = g(2)B
f(2) = g(0) and f(0) = g(4)C
f(2) = g(0) and f(4) = g(2)D
f(2) = g(4) and f(1) = g(1)6
Which represents the inverse of the function f(x) = 4x?

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).
A
f(–3) = g(–4)B
f(–4) = g(–3)C
f(–3) = g(–3)D
f(–4) = g(–4)8

Two functions are graphed on the coordinate plane.
A
f(4) = g(4) and f(0) = g(0)B
f(–4) = g(–4) and f(0) = g(0)C
f(–4) = g(–2) and f(4) = g(4)D
f(0) = g(–4) and f(4) = g(–2)
