Evaluate the functions for the values of x given as 1, 2, 4, 8, and 16. Describe the differences in the rate at which each function changes with increasing values of x. f(x) = 5x -3 f(x) = x^2 -3x +2

You can put this solution on YOUR website! f(x)=5x-3
f(1)=5*1-3
f(1)=5-3=2 ans.
f(2)=5*2-3
f(2)=10-3=7 ans.
f(4)=5*4-3
f(4)=20-3=17 ans.
f(8)=5*8-3
f(8)=40-3
f(8)=37 ans.
f(16)=5*16-3
f(16)=80-3
f(16)=77 ans.
------------------------
f(x)=x^2-3x+2
f(1)=1*2-3*1+2
f(1)=2-3+2
f(1)=4-3=1 ans.
f(2)=2^2-3*2+2
f(2)=4-6+2
f(2)=0 ans.
f(4)=4^2-3*4+2
f(4)=16-12+2
f(4)=6 ans.
f(8)=8^2-3*8+2
f(8)=64-24+2
f(8)=66-24=42 ans.
f(160=16^2-3*16+2
f(16)=256-48+2
f(16)=258-48=210 ans.
