Ans A

look at the graph for x = 2.... 
2^4 = 16 ..and the graph looks like it approx = 8 for x=2 
this suggests (1/2)x^4 
you can eliminate answers C and D straight off because the graph is never negative

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.

If k represents a number then write an expression for the ratio of 3 less than k to 2 more than k

EleoNora [17]

The key words you should notice when looking at this word problem are “less than.” This means that the order is flipped, so “3 less than k” means “k minus 3.”

The expression for the ratio is k-3:k+3
