Question

here is a graph of y=x^2-7x+10 for values of x from 0 to 7. 7a write down the roots of x^2-7x+10=0 7b write down the x-coordinate of the turning point

Answer 1

Answer:

Given:

x

2

+7x+10=0

x=

2(1)

−7±

(7)

2

−(4)(1)(10)

x=

2

−7±

49−40

x=

2

−7±

9

x=

2

−7±3

x=

2

−7+3

and x=

2

−7−3

So, the answer comes out to be, x=−2 and x=−5
