Answer:
Explanation:
o find the vertex of f(x)=x2−8x+7 , there are several things you can do. You could complete the square to get the equation into vertex ...
(3,5)
5x+3y=15
5(0)+3y=15
3y=15
divide both sides by 3 and you get y=5
5x+3(0)=15
5x=15
divide both sides by 5 and get x= 3
So then the y-int is 5 and the x-int is 3.
