F(x) = 1
g(x) = x - 4
can you evaluate (gof)(0)? explain why or why
not.

answer: yes. (gof)(0) = -5

(gof)(0) means you will find the function of g(f( which means we will find f(0) and plug that value in for x in the function g(x)

we know f(0) is -1, so we can plug -1 into the equation of g(x)

(gof)(0) = (-1) - 4

(gof)(0) = -5

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
