Answer:
B
Step-by-step explanation:
In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:

Now we just need to solve for b:
and
so

Y=ln(ln(x))
y'=(1/x)/Ln(x)=1/xln(x)
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
-0.65
-3/8
2/4
5/16
I hope this is right, the negatives should go first because you are taking away, then positives
