Question

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

Answer 1

"

$\huge \boxed{ \sf \blue{f( - 1) = 10}} \\ \huge \boxed{ \sf \green{f(0) = 3}}$

Step-by-step explanation:

f(x) = 3 - 5x + 2x²

.

To find -

f(-1) and f(0) for f(x)

.

Solution -

f(x) = 3 - 5x + 2x²

f(-1) = 3 - 5(-1) + 2(-1)²

=> 3 - (-5) + 2(1)

=> 3 + 5 + 2

=> 10

.

Hence f(-1) = 10

.

f(0) = 3 - 5(0) + 2(0)²

=> 3 - 0 + 0

=> 3

.

Hence f(0) = 3

.
