Step-by-step explanation:
Answer:
f(2) = 0
Step-by-step explanation:
Evaluate the function at x = 2.
f(x) = -3x^2 + 6x
f(2) = -3(2^2) + 6 * 2
f(2) = -3(4) + 12
f(2) = 0
This is pretty obviously

If it wasn't obvious we can find the common ratio r by dividing successive values:
5/1=5
25/5=5
125/25=5
625/125=5
That's the common ratio. We multiply by the first term, but the first term is one, so that has no effect.
You can write the expression 6(y) in the following ways:
6 × y
y × 6
6y
Answer:
27
Step-by-step explanation:
-21/-7 =3 so x is 3y. if you plug 9 in for y you get 3(9) then you multiply and get 27.
