Which two equations represent a nonlinear function? y=2(x−1)+1

y = 2 ( x − − 1 ) + 1

y=2x−1

y = 2 x − − 1

y=(x−1)2

y = ( x − − 1 ) 2

y=x−1

y = x − − 1

y=3x−1

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 correct answer is c
