Answer:
domain is all real x ≥ 0,
range is all real y ≥ 100
Step-by-step explanation:
Domain is what the variable (in this case x) can be
Range is the value of a function (in this case y) can be for any x
since x is ur babysitting hours, it cannot be -ve
x ≥ 0
y is money in ur bank account n y=10x+100
at x=0, y=10(0)+100=100
n as x increases, y increases as well
x ≥ 0, y ≥ 100
