- h is the number of hours John works
- f(h) is the function for the amount of money John earns
with this information provided all we have to do now is substitute
[tex]f(1):\\h=1 \\f(h) = 10h\\f(1) = 10*1 = 10[/tex]
so, first row:
[tex]f(h)=10 \\ h=1[/tex]
we repeat the same process with the rest of the values
[tex]f(4.5)\\h=4.5\\f(h)=10h\\f(4.5)=10*4.5 = 45[/tex]
second row:
[tex]f(h)=45\\h=4.5[/tex]
repeat that once more
[tex]f(10)\\h=10\\f(h)=10h\\f(10)=10*10= 100[/tex]
third and final row:
[tex]f(h)=100\\h=10[/tex]
and we're done, hope this helps. <3
