Wilson and Alexis can both by correct if the the function is a parabola. It can have zeroes at points x=-1, and x=1. Thus, the average rate of change between the two points would be zero because the y values do not change as they are both zero. In this way, Wilson is correct. Alexis can be correct because the parabola can have it's highest point at its vertex between the two points. It would count as a turning point because the function would increase and then decrease again.
Hope this helps :)
4(9x+1) would be the correct way to write the expression in distributive property.
Answer:
A= 15 root 5 - 10 ÷ 41
Multiply (3 root 5 - 2) top and bottom. Simplify
B= - 2
Multiply (root 3 + root 5) top and bottom. Simplify
C= 6x - 3 root xy ÷ 4x - y
or
3x - 3 root xy ÷ 2x - y
(because 6 & 4 is Divisible by 2)
Multiply (2 root x - root y) top and bottom. Simplify
Root means a square root - so, replace the word root with a square root!
Hope this helps!
For this case we have the following functions:
We must find the following sum of functions:
(f + g) (x)
By definition we have to:
So, we have to:
