Answer:
It is f(x) = -x^2 + 2x + 4.
Step-by-step explanation:
As it has a maximum the coefficents of x^2 will be negative.
f(x) = -x^2 + 2x + 4
The y-intercept occurs when x = 0 so
y-intercept = 0 + 0 + 4 = 4.

Answer:
12
Step-by-step explanation:
h'(x) = [f(x)*g(x)] '=f'(x )g(x) + f(x)g'(x)
h'(1) = [f(1)*g(1)] '=f '(1)g(1) + f(1)g'(1)
From the table f '(1)= -3, g(1)=2, f(1)= 3, g'(1) =6
h'(1) = f '(1)g(1) + f(1)g'(1) = -3*2 + 3*6= - 6+ 18 = 12
Answer:
4 yds
Step-by-step explanation:
So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)
and she cuts 9 pcs of ribbon each 4 feet
so it's 9 x 4 = 36
48 - 36 = 12
And 12 feet equals 4 yards
So, Joy has 4 yards of remaining ribbon
