Question

I need help with this question I don't understand

Answer 1

g(-1) = 1

Explanation:

Given polynomial:

• g(x) = x³+6x²+12x+8

Evaluating x = -1 on the given polynomial,we obtain

• g(-1) = -1³ + 6(-1)² +12(-1) + 8

Simplifying using PEMDAS,

• g(-1) = -1*-1*-1 + 6(-1*-1) + 12(-1) + 8
• g(-1) = -1 + 6*1 + (-12) + 8
• g(-1) = -1 + 6 -12 + 8
• g(-1) = 5 - 4
• g(-1) = 1

Hence,the function's value is 1.

Answer 2

g(-1) = 1

Explanation:

We can substitute x = -1 into g(x) to find g(-1).

g(-1) = (-1)³ + 6(-1)² + 12(-1) + 8 = -1 + 6 - 12 + 8 = 1
