Answer:

The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.

Step-by-step explanation:

The given function is

$y=2x^2-5$

To find the points which lie on the function, put difference values of x in the given function and find the values of y.

Put x= -2

$y=2(-2)^2-5=2(4)-5=8-5=3$

Put x= -1

$y=2(-1)^2-5=2(1)-5=2-5=-3$

Put x= 0

$y=2(0)^2-5=2(0)-5=-5=-5$

Put x=1

$y=2(1)^2-5=2(1)-5=2-5=-3$

Put x= 2

$y=2(2)^2-5=2(4)-5=8-5=3$

The table of values is shown below.

Plot these points on a coordinate plane and connect them by a free hand curve.

The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.

The graph of function is shown below.

Write a quadratic function in standard form with zeros 9 and -4

OverLord2011 [107]

$if\ x_1\ and\ x_2\ zeros,\ then\ quadratic\ function\:\\\\f(x)=a(x-x_1)(x-x_2)\\\\\\9;\ -4-zeros,\ then:\\\\f(x)=a(x-9)(x+4)=a(x^2+4x-9x-36)=a(x^2-5x-36)\\\\\\if\ a=1\ then\ f(x)=x^2-5x-36$
