Answer:
g o f = -[f(x)]² + 3 = -(|x|)² + 3 = -x² + 3 = g(x)
Step-by-step explanation:
g o f = g [ f(x) ]
This means replace the x of g(x) with f(x):
g o f = -[f(x)]² + 3 = -(|x|)² + 3
As x² ≥ 0 for any value of x (whether it be positive or negative), then -(|x|)² + 3 = -x² + 3 = g(x)
So g o f = g(x)
7x + 3 is the final answer
My best possible answer choice should be B
Answer:
-13y-3
Step-by-step explanation:
(-4y - 1) + (-9y -2)
remove parenthesis
-4y - 1 + -9y -2
combine like terms
-13y - 1 - 2
now we subtract -1 -2 = -3 so
-13y- 3
