Let fx 2x1 x 2 Compute the following function valuesSolution

Let f(x) ={2x-1, x -2 Compute the following function values:

Solution

a) 0 is greater than -2 so f(x)=x^2+1 will be used

f0)=0^2+1=1

b) equality at x=-2 so 2x-1 will be used

f(-2)=2(-2)-1

=-4-1

=-5

c) 2 is greater than -2

f(2) =2^2+1

=5

d)-3 is less than -2

f(-3)= 2(-3)-1

=-6-1

=-7
