Question

If f(x)=3x^5-2x^3+1, then f(-1)=?

Answer 1

Answer:

f(-1) =0

Step-by-step explanation:

f(x)=3x^5-2x^3+1

Let x = -1

f(-1) = 3(-1)^5 -2(-1)^3 +1

      = 3(-1) -2(-1)+1

        =-3 +2+1

        =0

Answer 2

Answer:

f(-1)=0

Step-by-step explanation:

f(x)=3x^5-2x^3+1

well, all you have to do is to replace x with -1.

f(-1)=3·(-1)^5-2·(-1)^3+1

f(-1)=3·(-1)-2·(-1)+1

f(-1)=-3+2+1

f(-1)=-3+3=0
