A - actuary...........that is the answer
F (x)=2-3x
find f (4)
or x=4 find f (x)
2-3 (4)
2-12= -10
Answer:
C
Step-by-step explanation:
First you have to find h'(x). To find it you have to use the multiplication differentiation rule. Therefore h'(x) is...
h'(x) = f(x)g'(x) + g(x)f'(x)
Then plug 2 into the equation
h'(2) = f(2)g'(2) +g(2)f'(2)
Then you use the graphs to find out the numerals for the equation
f(2) = 4
g(2) = 5
To find the derivative of these functions, you have to find the slope of the line at the point where x = 2
f'(2) = 2
g'(2) = 1
Then finally you plug that all into the equation we made at the beginning and get the answer
h'(2) = 4 x 1 + 5 x 2 = 14
So the answer is C

The slope is two, but it can be written as 2/1
Answer:
= y^2 -18y +81
Step-by-step explanation:
(y–9)^2
(y-9) (y-9)
FOIL
first: y*y = y^2
outer: -9y
inner: -9y
last: -9*-9 = 81
Add them all together = y^2 -9y-9y+81
= y^2 -18y +81
