Question

If f (x) = x square - 4x + 6 find f (1) - f (-1) Please help fast

Answer 1

Answer:

-8

Step-by-step explanation:

The value of f(1) - f(-1) is -8.

Step-by-step explanation:

The given function is

We need to find the value of f(1) - f(-1).

Substitute x=1 in the given function .

Substitute x=-1 in the given function .

The of f(1) - f(-1) is

Therefore, the value of f(1) - f(-1) is -8.

Answer 2

Answer:

given f(x)=x^2-4x+6

put x=1 then

f(1)=(1)^2-4(1)+6

=1-4+6

=3

put x=-1 then

f(-1)=(-1)^2-4(-1)+6

=1+4+6

=11

f(1)-f(-1)

=3-11

=-8

therefore answer is -8
