The function f(x) is graphed on the coordinate plane. what is f(−4) ? enter your answer in the box. f(−4) =

For this case, what you should do is observe in the graph the value of the function when x = -4.

The value of the function is observed when looking at the vertical axis.

Remember that in a function of the form y = f (x) we have:

x: independent variable

y: dependent variable.

Therefore, for x = -4 we have:

f (-4) = 4

The value of the function evaluated at x = -4 is given by:

f (-4) = 4

the answer is 15% decrease
