If f(x)=x^2-2x+11, find f (-2)

 f( -2) = 19

Step-by-step explanation:

plug '-2' into every place 'x'  is in

so the new equation would be

f(-2) = (-2)^2 - 2(-2) + 11

and now solve :)

f ( -2) = 4 - ( -4) + 11

f (-2) = 4 + 4 + 11

f ( -2 ) = 19

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
