Think about this as a table of values where domain is the x values and range is the y values.
f(4) wants the y-value when the x-value is 4
f(4) = 1/2
The second question wants us to find the x-value when f(x) also known as the y-value is 4.
f(x) = 4
x = 8
answers: 1/2, 8
We are given
Clare is paid $90 for 5 hours of work
Total money paid =$90
total hours of work =5 hours
so, firstly we will find rate of work
rate of work = ( total money paid)/( total hours of work)
now, we can plug values
and we get
The rate of work is

$/ hour
now, we have to find time for amount paid is 25 cents
so, amount paid =25 cents
100 cents =1$
so, amount paid =$ 0.25
Since, the rate is constant
so, we can take same rate here
now, we can use formula
rate of work = ( total money paid)/( total hours of work)
now, we can plug values

now, we can solve for T
hour
since, T is in hours
so, we can change into seconds
1 hour =3600seconds
so, we can plug
seconds
seconds......................Answer
