You would substitute or plug in -5 wherever there is an x in the equation.
f(-5) = 6(-5) + 7
f(-5)= -30 + 7
f(-5) = -23
(-9x²-2x) - (-9x²-3x) = (-9x²-2x) +(9x²+3x) = -9x²-2x+9x²+3x = (-9x²+9x²)+(-2x+3x) = x
(2, -1), (6,- 4), and (6, -1). Hope this helps man!
Plug in g equals -5 x -2 which equals 10 because 2 negatives are a positive then 10-6 equals 4
The anwser is 4
