Question

Dorian earns $15 every time he walks a dog. He models the total amount of money he makes walking dogs with the equation f(w)=15w . Which inequality shows the range of his earnings given the real-world constraints?(1 point)Responses0<f(w)<1,050 0 less than f left parenthesis w right parenthesis less than 1,0500≤f(w)≤1,050 0 less-than-or-equal-to f left parenthesis w right parenthesis less-than-or-equal-to 1,0500≤f(w)<∞ 0 less-than-or-equal-to f left parenthesis w right parenthesis less than infinity−∞<f(w)≤1,050 negative infinity less than f left parenthesis w right parenthesis less-than-or-equal-to 1,050

Answer 1

0 ≤ f(w) < ∞

Reason: w (number of dogs) can't be negative, so f(w)=15w ≥ 0. No maximum number of dogs is given, so earnings can grow without bound.
