What are the domain and range of the step function with the equation below?
Ax)=-3[x7

6 and 24

step-by-step explanation:

6 x 4 = 24

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:

using pemdas, (order of operations) you'll see the answer is 24.
