Question

When g ( t ) = 3 t 2 + 2 t + 1 , evaluate g ( − 4 )

Answer 1

Just substitue every 't' with -4

Explanation:

g(-4) = 3*(-4)*(-4) + 2*(-4) + 1

g(-4) = 64-8+1

g(-4) = 57

Answer 2

g(-4) is 41

Explanation:

`g(t) = 3 {t}^(2) + 2t + 1`

when t is -4, substitute -4 in place of t:

`g( - 4) = 3 {( - 4)}^(2) + 2( - 4) + 1 \\ g( - 4) = 48 - 8 + 1 \\ g( - 4) = 41`
