Question

If f(x) = 2-x^2 + x^3 and f(a) = 2, then what are the the possible values of a?
I dont get it, at all. Show workkk!

Answer 1

2-a^2+a^3=2
-a^2+a^3=0

Answer 2

so when a=0 , 0=0

Answer 3

a^3=a^2
1=1

Answer 4

so 0,1

Answer 5

2-x^2 + x^3 = 2
-x^2 + x^3 = 0
x^2(-1 + x) = 0
x^2 = 0, x = 0
-1 + x = 0, x = 1
x = 0, 1

Answer 6

a could also be 1
