Since we have (5,3), f(5)=3
f'(5) is the slope of the line at x=5
we are given that the line tangent to f(x) at x=5 passes through the point (0,2)
so find the slope of that line
we know it passes through (5,3) and (0,2)
slope between

and

is

slope between (5,3) and (0,2) is [/tex]\frac{3-2}{5-0}=\frac{1}{5}[/tex]
f(5)=3
f'(5)=
2x - 30 = -2(x + 3) =
2x - 30 = -2x - 6
2x + 2x = -6 + 30
4x = 24
x = 24/4
x = 6
The answer is C 9/2 x 1/3
The answer is A. Y=2x+2
Because the slope is 2 and it crosses the Y axis at 2
Answer: The domain has to be x and the range y. But for independent and dependent variable I can't help. So srry. The picture doesn't show the work. Have a nice day :)
