Question

When f(x) = 6x² + 6x + 3, evaluate f( – 5)​

Answer 1

f(-5) is 123

Explanation:

`f(x) = 6 {x}^(2) + 6x + 3`

when x is -5, f(x) is f(-5) :

`f( - 5) = 6 {( - 5)}^(2) + 6( - 5) + 3 \\ = 150 - 30 + 3 \\ = 123`

Answer 2

Explanation:

f(x) = 6(-5)^2 + 6(-5) + 3

f(x)= 6(25) - 30 + 3

f(x)= 150 - 27

f(x)= 123
