Look at the image pls help

i need the formula to help i promise i will but i need the formula for the slanted f

Step-by-step explanation:

is 34

Step-by-step explanation:

^<- this is the square sing

f(1)+f(-2) for f(x)=4x^2+7

f(1)=4(1)^2+7

=4+7

f(1) =11

f(-2)=4(-2)^2+7

if you square -2 there will not be no -

-2 the whole square is 4

=4(4)+7

f(-2)=23

f(1)+f(-2)=11+23=34

:. The answer is 34

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
