Question

a school club is raising money for a trip, and needs to reach $10,000. their fundraising progress is modeled by the function ( f(x)=435 + 1200x), where (x) is measured in weeks. what is the meaning of the constant 435? a it is the amount they started with. b it is the amount still to be raised. c it is the amount which is left over. d it is the amount they raise each week.

Explanation:

In a linear - function of the form $y = mx + b$ (here $f(x)=1200x + 435$), $b$ is the y - intercept. When $x = 0$ (at the start, i.e., 0 weeks have passed), $f(0)=435$. So 435 is the initial amount of money the school club had before starting the weekly fundraising.

Answer:

A. It is the amount they started with.
