If f(x) = x + 4 and g(x) = x2 -1, what is (gof)(x)? o (gºf)(x)=x2-1
o (gºf)(x) = x+8x+16
. (gºf)(x) = x² +8x+15
O (gºf)(x) = x+3

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
