Question

2. If g(x) = x2 – 3x + 2, find g(-4).

Answer 1

30

Explanation:

Please write this g(x) = x2 – 3x + 2 as g(x) = x^2 – 3x + 2. The ^ indicates exponentiation.

Evaluate g(-4) by replacing all instances of x by -4:

g(x) = (-4)^2 – 3(-4) + 2, or

g(x) = 16 + 12 + 2 = 30

Answer 2

42

Explanation:

you plug in -4 into x and multiply

ex: (-4)2-3(-4)+2
