Evaluating Functions Answers

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

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

The table represents the function f(x).

Which statement is true regarding the graphed functions?

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).

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).

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

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

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

Two functions are graphed on the coordinate plane.
