6. If g (x) = 2x2+x-12, find g (5).

-3

Step-by-step explanation:

2x2 + (5) - 12

4 + (5) - 12

9-12

-3

In this question, you're going to plug in 5 to the x variables and solve.

Plug in 5 into the x variables:

g (x) = 2 (5) ² + 5 - 12

Solve:

g (x) = 2 (5) ² + 5 - 12

Note: (5) ² is equivalent to 5 * 5

g (x) = 2 (5*5) + 5 - 12

g (x) = 2 (25) + 5 - 12

g (x) = 50 + 5 - 12

g (x) = 55 - 12

g (x) = 43

Answer:

g (x) = 43
