Question

Given the following functions, find the indicated values.

f(x)=3-2x
(a) f(-4) (b) f(0) (c) f(8)

Answer 1

• a) f(-4) = 11
• b) f(0) = 3
• c) f(8) = -13

Explanation:

a) The value of f(-4) is?

→ f(x) = 3 - 2x

→ f(-4) = 3 - 2(-4)

→ f(-4) = 3 + 8

→ [ f(-4) = 11 ]

b) The value of f(0) is?

→ f(x) = 3 - 2x

→ f(0) = 3 - 2(0)

→ f(0) = 3 - 0

→ [ f(0) = 3 ]

c) The value of f(8) is?

→ f(x) = 3 - 2x

→ f(8) = 3 - 2(8)

→ f(8) = 3 - 16

→ [ f(8) = -13 ]

Hence, these are the values.
