Function Notation and Evaluating

How would you write y = 2x - 3 in function notation?

• y = 2x-3

• f = 2x - 3

• f(x) = 2x-3

f(x)=4x+5
f(4)=

• 21
• -11
• -31
• 25

If f(x) = 2x² + 5x - 3, evaluate f(-1).

• f(-1) = -6

• f(-1) = 1

• f(-1) = -10

• f(-1) = -1

Evaluate f(-2) if f(x) = x²+ 3

• -1

• 1

• 7

• -7

If h(x) = -5x + 7,

Evaluate h(2).

• -2

• 3

• -18

• -3

For the function f(x) = -3x + 3 find f(0).

• 0
• -3
• 3
• -1

• 1

• 2

• 3

• 4
