What is the vertex of the function x2 - 6x + 8 = 0?

The vertex of the function is (h,k) = (3 , -1)

Solution:

The vertex form of quadratic equation is generally given as,

Where h,k is the vertex of the parabola.

From question, given that .

we have to find the vertex of the function.

Let us first convert the given quadratic equation to vertex form (eqn 1)

By adding “9” on both sides of equation, we get

By using the identity ,the right hand side of above equation becomes,

Now,the equation is of the vertex form.

By comparing with

we get the values of (h,k)

a = 1; h = 3; k = -1

hence the vertex of the function is (h,k) = (3 , -1)

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
