F(x) = -3x^2 + 6x. Find f(2).
inysia [295]

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

What is my equation
Vinil7 [7]
This is pretty obviously

f(x) = 5^x

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.

f(x)=5^x
