Which graph represents an exponential function? On a coordinate plane, a line curves upwards gradually. On a coordinate plane, a curve decreases, changes directions, and then decreases again. On a coordinate plane, a line is level and then curves upwards rapidly. On a coordinate plane, 2 curves mirror each other in quadrants 1 and 3. Mark

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.
