For each function, find f(-2), f(-0.5), and f(3).

1. f(x)=-x+4

2. f(x)= 3/8x-3

 The calculations are done below.

Step-by-step explanation: We are given to find the values f(-2), f(-0.5) and f(3) for each of the given functions.

The first function is

So, we get

The second function is

So, we get

Thus, all the values are found.

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
