Question

find the value of find the value of f (-1) + f (0) if
f (x) = 3 - 5x + 2x²​

Answer 1

Answer:

12

Step-by-step explanation:

first put the value of f(-1) in given equation

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

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

=3 + 5 + 2

=9

then put f(0) in given equation

f(0)= 3 -5(0) + 2(0)^2

=3

then add both values

f(-1) + f(0)

9 + 3
