<u> Solution-</u>
The given function is,






Therefore, at x=0, -1, 1 , f(x) will be 0 . Hence, 0, -1 ,1 are the x-intercepts.
Plotting the graph on desmos, the graph will be as in the attachment.
Answer:
x < 11.5
Step-by-step explanation:
2x + 9 < 32
(2x + 9) - 9 < 32 - 9
2x < 23
2x/2 < 23/2
x < 11.5
Answer:
I believe "The height of each pyramid is one-half h units"
We will use u-substitute:

Then for substitution:dx=u du. and integral becomes:

=u-ln(u+1)=

. Now we will change the values of limits:

=4-ln(5)-2+ln(3)=
2+ln(0,6)=2-0.51=1.49
114
1^3 + 1^3 + 4^3 = 1 + 1 + 64 = 66
99 - 66 = 33
33/3 = 11
1 + 1 = 2
I am not sure of the exact way to solve this....I just did it by trial and error
