Question

let ( g(x) = 2x^2 - 11x ). find ( g(-1) ).
a (-13)
b (-9)
c (0)
d (9)
e (13)

Explanation:

Step1: Substitute \( x = -1 \) into \( g(x) \)

We have the function \( g(x) = 2x^2 - 11x \). Substitute \( x=-1 \) into the function: \( g(-1)=2(-1)^2 - 11(-1) \)

Step2: Calculate each term

First, calculate \( (-1)^2 = 1 \), so \( 2(-1)^2=2\times1 = 2 \). Then, \( - 11(-1)=11 \).

Step3: Sum the terms

Add the two results together: \( 2 + 11 = 13 \)

Answer:

E. 13
