After m months, the height of a plant is 10+3m. How tall is the plant after one year?
1 year is 12months ,plug in months
10+3(12)
10+ 33
43
For this case we have the following equation:
p (x) = 8 + 6x-4x2
We must derive the equation to find the maximum of the function.
We have then:
p '(x) = 6-8x
We match zero:
6-8x = 0
We clear x:
8x = 6
x = 6/8
x = 3/4
x = 0.75 speakers
