Question

Give the following sequence for f(x) = 4x^2 - x , when x is -4, 1, 2

O 58, 14, 3
0-64, - 14, 3
O 68, 14, 3
0 7, 14, 3

Answer 1

O 68, 14, 3

Explanation:

Given:

f(x) = 4x² - x

When x = -4

f(x) = 4x² - x

= 4(-4)² - (-4)

= 4(16) + 4

= 64 + 4

f(x) = 68

When x = 1

f(x) = 4x² - x

= 4(1)² - 1

= 4(1) - 1

= 4 - 1

f(x) = 3

When x = 2

f(x) = 4x² - x

= 4(2)² - 2

= 4(4) - 2

= 16 - 2

f(x) = 14

The answer = 68, 3, 14
