Question

If g(x) = 4x2 + 3x - 25, what is the value of g(-10)?

F -445
G 25
H 1545
J 345

Answer 1

g(-10) = 345

Explanation:

g(x) = 4x² + 3x - 25

~Substitute

g(-10) = 4(-10)² + 3(-10) - 25

~Simplify

g(-10) = 4(100) - 30 - 25

~Multiply

g(-10) = 400 - 30 - 25

~Subtract

g(-10) = 370 - 25

~Subtract

g(-10) = 345

Best of Luck!
