Answer:

2 hours if they go to school.

10 hours if they dont go to school.

9/2+5/2=14/2=7hours +7 hour of sleep= 14 hours.

if they go to school for 8 hours then add 8. then it =22 hours witch gives you 2 hours

if they dont go to school then you got 24-14 hours=10 hours.

The graph of the function F(x) = 2x^2-8 is changed. The new graph can be
vova2212 [387]

Answer:

The graph now opens in the opposite direction. The y intercept is shifted up 4.

Step-by-step explanation:

F(x) = 2x^2-8

F(X)= -2x^2-4

We know that the graph is reflected over the y-intercept becuase of the negative sign in the second equation ( F(X)= -2x^2-4)

We know that the intercept is shifted up four, because the number decreased from 8 to 4, and the graph is reflected.

Attacthed is both of the equations graphed to help you visualize this shift!
