Nolan Ellison · Answer 1

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

Malcolm Cannon · Answer 2

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
