I need help hurry When compared to the graph of f(x) = x², the graph of g(x) = ax² + c is a vertical stretch by a
factor of 7 and a vertical translation downward by 3 units.
Find a - c.

Step-by-step explanation:

a = 7

c = -3

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
