Question

Use the piecewise-defined function to find the fallowing values for f(x)F(x) =.{. 5-4x if x<1 4x if 16F(-3) =

Answer 1

To look for f(-3) we are going to use the first portion of the formula

f(x) = 5 - 4x, because here we will find all the x - values from -∞ to 1

So

f(-3) = 5 - 4 (-3) = 5 + 12 = 17
