The function is [tex]C(x)=7x[/tex]
Step-by-step explanation:
Given : Charles will babysit for up to 4 hours and charges $7 per hour.
To find : Write a function in function notation for this situation ?
Solution :
Let the work done by Charles in 'x' hour.
The charges is $7 per hour.
To create a function of x,
The cost function of 'x' hour is [tex]C(x)=7x[/tex]
Charles will babysit for up to 4 hours.
So, The cost for 4 hour is [tex]C(x)=7\times 4[/tex]
[tex]C(x)=\$28[/tex]
