Question

Evaluate each function. 14) g(x)= 3x² - 1; Find g(-3)

Answer 1

$g(x) =3x^2 -1\\\\g(-3)=3(-3)^2 -1 \\ \\~~~~~~~~~=3(9) -1 \\\\~~~~~~~~~=27-1\\\\~~~~~~~~~=26$

Answer 2

Answer:

g(26)

Step-by-step explanation:

 

substitute -3 for x.

g(x)=3$x^{2}$-1

$g(-3)=3(-3)^{2} -1\\g(-3)= 3(9)-1\\g(-3)= 27-1\\g(-3)=26$
