What is the vertex of the quadratic function below? y=x^2-8x+1 a. (-8,129) b. (8,1) c.( 4,-15) d. (-4,15)

The correct answer is C. (4, -15)

Step-by-step explanation:

In order to find any vertex, start by finding the x value. We can do this by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.

-b/2a

-(-8)/2(1)

8/2

4

Now we know the value of x is 4. This gives us the only option being C

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
