Is 3x^2 + x^2 equal to a) 3x^4 b) 4x^2 (^2 means to the second power ) (^4 means to the fourth power)

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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.
