Question 958654
 {{{f(x)=1-e^(-x)}}}

 {{{f(x)=1-1/e^x}}}

make a table:

{{{x}}}| {{{f(x)}}}

{{{-4}}}| {{{-53.59}}}...{{{f(-4)=1-1/e^(-4)=1-1/(1/e^4)=1-e^4=1-54.59=-53.59}}}

{{{-3}}}| {{{-19.08}}}....{{{f(-3)=1-1/e^(-3)=1-1/(1/e^3)=1-e^3=1-20.08=-19.08}}}

{{{-2}}}| {{{-6.39}}}....{{{f(-2)=1-1/e^(-2)=1-1/(1/e^2)=1-e^2=1-7.39=-6.39}}}

{{{0}}}| {{{0}}}....{{{f(0)=1-1/e^(0)=1-1/1=1-1=0}}}

{{{2}}}| {{{0.86}}}....{{{f(2)=1-1/e^(2)=1-1/7.39=1-0.14=0.86}}}

{{{3}}}| {{{0.95}}}....{{{f(3)=1-1/e^(3)=1-1/20.08=1-0.05=0.95}}}

{{{4}}}| {{{0.98}}}....{{{f(4)=1-1/e^(4)=1-1/54.59=1-0.018=0.98}}}

plot these pints and draw a line through
