135.30 dollars is the total cost
(6, 2)
because a midpoint is the middle of a line, you take the difference between the y coordinates (the x-coordinates are the same so no need to worry ‘bout that) and subtract from the midpoint. 8-5=3 and 5-3=2.
Answer:
-6 only
Step-by-step explanation:
f(0) is the value of y when x=0. This is the graph of a 4th-degree polynomial, so is a function. There is only one y-value for x=0. That is where the graph crosses the y-axis, at y = -6.
f(0) = -6 . . . . only
Step-by-step explanation:
g(x)= -16x² + 72x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 72(2) + 80
-16(4)+128+80
-72+128+80
= 136
