Please help! Will give 90 points Write the equation of the piecewise function ƒ that is represented by its graph.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the answer is  

c.

14,469 cubic feet

i know this one is right

you need to know that the corresponding sides and angles are the same.
