D1-Evaluating Functions

Front

If f(x) = 6x + 7, find f(3).

Back

f(3) = 6(3) + 7 = 18 + 7 = 25.

Front

Evaluate f(33) if f(x) = 3x - 5.

Back

f(33) = 3(33) - 5 = 99 - 5 = 94.

Front

What is the value of f(0) if f(x) = 2x + 4?

Back

f(0) = 2(0) + 4 = 0 + 4 = 4.

Front

If f(x) = 3x - 5, find f(4).

Back

f(4) = 3(4) - 5 = 12 - 5 = 7.

Front

g(x) = 5 - 6x. Find g(-5).

Back

g(-5) = 5 - 6(-5) = 5 + 30 = 35.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b.

Front

What is the slope of the function f(x) = 2x + 3?

Back

The slope is 2, which indicates the rate of change of the function.

Front

What is the y-intercept of the function f(x) = -x + 4?

Back

The y-intercept is 4, which is the value of f(0).

Front

If f(x) = x^2, what is f(2)?

Back

f(2) = 2^2 = 4.
