The vertex form of the equation of a parabola is y = (x - 3)2 + 36. What is the standard form of the equation?
A. y = x2 + 6x + 36
B. y = x2 + x + 18
C. y = 3x2 - 6x + 45
D. y = x2 - 6x +45

A

Step-by-step explanation:

y=(x-3)2+36

y=2x+6x+36

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.
