Hi. I need help with these
See image for question
Answer no 8 ,9 and 10

Step-by-step explanation:

8.

Given

The sum of the roots is α + β = -q/p, the product of then roots αβ = r/p

9.

Given function

The minimum point is reached at vertex

The vertex is:

The corresponding y-coordinate is:

So the point is:

10.

Given function

The maximum is reached at vertex

The vertex is:

The corresponding y-coordinate is:

So the maximum point is:

eve and marks ratios are equivalent

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
