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.

Is the line through points P(0, 1) and Q(5, 0) parallel to the line through points R(–4, 3) and S(–5, 4)? Explain.

Answer:

No

Step-by-step explanation:

Let's find the slope of both lines and then compare these slopes:

From (-4,3) to (-5,4) entails a decrease of -1 in x and an increase of 1 in y.  Thus, the slope is m = rise / run = 1/(-1) = -1.

From (0,1) to (5,0) entails an increase of 5 in x and a decrease of 1 in y.  The slope here is m = rise / run = -1/5.

For these lines to be parallel, their slopes must be the same.  That is not the case here, so NO, the lines are not parallel.
