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 + 23
On a coordinate plane, a red curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A blue curved line with an upward arc, labeled f of x, crosses the y-axis at (0, 4) and the x-axis at (2, 0).
A
f(0) = 2 and g(–2) = 0B
f(0) = 4 and g(–2) = 4C
f(2) = 0 and g(–2) = 0D
f(–2) = 0 and g(–2) = 04
Which represents the inverse of the function f(x) = 4x?
A
h(x) = x + 4B
h(x) = x – 4C
h(x) = x
D
h(x) = x

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)6
What is the inverse of the function f(x) = x + 2?
A
h(x) = 18x – 2B
h(x) = 9x – 18C
h(x) = 9x + 18D
h(x) = 18x + 2
