Question

i want to go with c

Which is the equation of the power function p(x) = ax^2 if p(3) = 36?
(Points : 1)
p(x) = 3x^2

p(x) = 4x^2

p(x) = 9x^2

p(x) = 12x^2

Answer 1

p(x) = ax^2
p(3) = 36

so when x=3, p is 36...

36 = a(3)^2

find a

Answer 2

36 / 3 = a(^2) ?

12 = a^2

px = 12x^2?

Answer 3

3^2 is 9.

Answer 4

4 = a

Answer 5

the answer is b
