Patrick is donating money a volunteering his time to an organization that restores homes. His employer will match his monetary donation up to $100. Write and graph a function for this situation.

Question

i think It may be  a linear function

Answer 1

Let d(c) be the function which calculates the total donation in dollars (including the employer's contribution). $c is Patrick's donation.

d(c) is a piecewise function:

d(c)={ 2c for 0≤c<100

        { c+100 for c≥100

c is the horizontal axis and d is the vertical axis.
