The functions f(x) and g(x) are graphed.

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

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

If f(x) = 5x + 40, what is f(x) when x = –5?

If f(x) = 6x – 4, what is f(x) when x = 8?

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

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).

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).

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