In interval <a, b> the average rate of change the function you count from this formula:

Here you've got a=-1 and b=1:
Hello!
You can distribute the 10
50x - 6 + 50
Combine like terms
50x = 44
Divide both sides by 50
x = 44/50
Simplify
x = 22/25 = 0.88
The answer is x = 0.88
Hope this helps!
Vertex = -b/2a = -(44)/2(-1) = -44/-2 = 22
To find the x-intercepts, set the function equal to 0 and solve for x
