Question

1.) The graph of g(x) = ax? opens downward and is narrower than the graph of f(x) = x? Which of the following

could be the value of a?
a. 5
b. 0.5
C. -5
d. -0.5​

Answer 1

C. -5

Explanation:

for g(x) =ax and f(x) = x, both are linear function. There is nothing to be upward or downward and both are lines nothing to compare its narrowness.

If g(x) = ax² vs f(x) = x²

Then a = -5 is the answer (-: downward and 5: vertical stretch)
