Question

Given g(x)=-2x^2+1 find the indicated value if g(-3)

Answer 1

-17

Explanation:

g(-3)= -2x(-3)^2+1

= -2x 9 +1

= -18 +1

= -17

Answer 2

g(2) = -7

g(-3) = -17

g(-4) = -31

Explanation:

g(x) = -2x^2 + 1

Subsitute the value in the bracket into the equation

g(2) = -2 * (2)^2 + 1 = -2 * 4 + 1 = -8 + 1 = -7

g(-3) = -2 * (-3)^2 + 1 = -2 * 9 + 1 = -18 + 1 = -17

g(-4) = -2 * (-4)^2 + 1 = -2 * 16 + 1 = -32 + 1 = -31
