The graph of a quadratic function is represented by the table.

x f(x)

6 -2

7 4

8 6

9 4

10 -2

What is the equation of the function in vertex form?

Substitute numerical values for a, h, and k.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

the answer is c 150
