D1-Evaluating Functions

Front

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

Back

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

Front

Which set of values is a function? (9,5) (10,5) (9,-5) (10,-5), (3,4) (4,-3) (7,4) (3, 8), (6,-5) (7, -3) (8, -1) (9, 1), (2, -2) (5, 9) (5, -7) (1, 4)

Back

(6,-5) (7, -3) (8, -1) (9, 1) is a function because each input has a unique output.

Front

Evaluate f(33) if f(x) = 2x - 55

Back

f(33) = 2(33) - 55 = 66 - 55 = 11

Front

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

Back

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

Front

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

Back

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

Front

What is a function?

Back

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

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for the function.

Front

If f(x) = x^2, find f(-3)

Back

f(-3) = (-3)^2 = 9

Front

If f(x) = 4x + 1, find f(0)

Back

f(0) = 4(0) + 1 = 1
