Write the equation of the sinusoidal function shown. Question 3 options: A) y = 2 sin(2x) B) y = 2 cos(2x) C) y = 2 sin x + 2 D) y = 2 cos x + 2

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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.
