Question

What is the value of f(-2) when f(x) = 2x2−3x+28

Answer 1

Answer:

f(x)=x−4x2−3x−28 f ( x ) = x - 4 x 2 - 3 x - 2 8 .

Step-by-step explanation:

Answer 2

Answer:

• f(-2) = 42

Step-by-step explanation:

Given function:

• f(x) = 2x²−3x + 28

Find f(x) when x = -2

• f(-2) = 2(-2)² - 3(-2) + 28 = 2(4) + 6 + 28 = 42
