2
Step-by-step explanation:
First, we must figure out the numerator of this fraction
(−5×7+9× 5)/5

-5*7= -35 9*5=45
Add
-35+45=10
Now do the long awaited division
10/5=2
Step-by-step:
Using PEMDAS:
(-5x7+9x5)/5
(-35+45)/5
10/5
225
25/7
8x^2-8.76x+2.92
Factor using FOIL and then simplify
The vertex of the function is
