Answer:
Both of them are correct.
Step-by-step explanation:
Isaac says that for the function, between x = -1 to x = 1, the average rate of changes is 0.
When a function has the average rate of change = 0 i.e. ,
We get that the function will have an extrema point i.e. a point at which the function will have the largest or smallest value i.e. the graph of the function changes its direction.
Further, Noah states that between x = -1 to x = 1, the graph goes up through a turning point and then goes back down.
This means that in x = -1 to x = 1, the function attains the maximum value at some point through which graph is changing its direction from upwards to downwards.
As, both Isaac and Noah are stating that there is a point in x = -1 to x = 1, at which the function attains its maximum value and the graph changes its direction.
Hence, both of them are correct.
Answer:
254
Step-by-step explanation:
Surface Area = 2Lh+2Lw+2wh
L=4 cm
h=9 cm
w=7 cm
Surface Area = 2(4)(9)+2(4)(7)+2(7)(9)
Surface Area = (72+ 56 +126)
Surface Area = (72+ 56 +126)
Surface Area =254
