Question

if g(x) = x²+ 3x - 6, find g(-7)

Answer 1

(-7)^2+3(-7)-6
49+3•(-7)-6
10

Answer 2

Answer:  g (-7) = 22

Step-by-step explanation:

If g(x) = x² + 3x - 6

Then g (-7) can be found by substituting -7 for x in g(x) and solving the equation

⇒ g(-7) = (-7)² + 3(-7) - 6

⇒ g (-7) = 49 - 21 -6

⇒ g (-7) = 22
