Answer:

• f(-8) = 22
• f(0) = 0

Step-by-step explanation:

Given : f(x) = x²- 3x

We have to find f(-8), f(0)

Simply substitute the value of x as - 8 and 0

• Putting x = -8

f(x) = x² - 3x

f(-8) = (-8)² - 3(8)

f(-8) = 46 - 24

f(-8) = 22

• Putting x = 0

f(x) = x² - 3x

f(0) = (0)² - 3(0)

f(0) = 0 - 0

f(0) = 0
