Which function has zeros at x=-2 and x=5

y=2.5x+5 or f(x)=2.5x+5

Step-by-step explanation:

We know 2 given points. (-2, 0) and (0,5)

With these two points we can calculate the slope:

0-5/-2-0+

-5/-2=

5/2 = 2.5

Because the y-intercept is given at 5, we can put these numbers into y=mx+b and get y=2.5x+5 or f(x)=2.5x+5

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
