Question

Which statement correctly compares the two functions given below?

Answer 1

\[f(x)=-24x-19\]
\[g(x)=-6x+14\]

Function g(x) decreases at a rate 4 times faster than function f(x).
Function f(x) decreases at a rate 4 times faster than function g(x).
Function g(x) decreases at a rate 18 times faster than function f(x).
Function f(x) decreases at a rate 18 times faster than function g(x).

Answer 2

hint : y = mx + b , m is the rate of change of the function (the slope)
