Evaluate the following expression:
-3x2 - 5x + 4 when x = -2

8

Step-by-step explanation:

Assuming your expression reads as negative 3 multiplied by 2 minus 5x plus 4 :

-3x2 =-6

5x(-2) = - 10

-6 - - 10 = 4

4 + 4 = 8

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.
