Aschool 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 coefficient 1200?
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.

D)It is the amount they raise each week

Step-by-step explanation:

Given : Their fundraising progress is modeled by the function

f(x) = 435 + 1200x, where x is measured in weeks.

To Find :What is the meaning of the coefficient 1200?

Solution :

f(x) = 435 + 1200x

Where x denotes the week

if 1200 is raised fund so 1200x is the fund raised in x weeks

Thus the coefficient 1200 means the amount they raise each week.

Thus Option D is correct .

D)It is the amount they raise each week

x intercept = (-1,0)   (4,0)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
