g(-2)=3(-2)-9

g (- 2) = 3 (- 2) - 9

g = \frac{15}{2}

Solution steps

g (- 2) = 3 (- 2) - 9

Remove parentheses:

(- a) = - a

g (- 2) = - 3 \cdot 2 - 9

Multiply the numbers:

3 \cdot 2 = 6

g (- 2) = - 6 - 9

Subtract the numbers:

- 6 - 9 = - 15

g (- 2) = - 15

Divide both sides by

- 2

g = \frac{15}{2}

f, f (x y) = x^{2} + y^{2}

2 z + 9 = 2 + 1

m - 5 = 14

y, 3 x - 2 y = - 12

x, y - 3 = - 2 (x + 1)
