Question

The value of f(x) = 4s−2s2+1 when s = -1, is:

Answer 1

Step-by-step explanation:

f(x) = 4s - 2s + 1

s = -1

=4(-1) - 2(-1) + 1

= -4 + 2 +1

=-4 +3

=-1 answer

Answer 2

Answer:

-5

Step-by-step explanation:

f(x) = 4s - 2s^2 + 1

put s = -1

f(-1) = 4 (-1) - 2(-1)^2 + 1

= -4 - 2 + 1

= -5
