Select the function that represents a parabola with zeros at x = –2 and x = 4, and y-intercept (0,–16). Question 1 options:

A)

ƒ(x) = x2 – 2x – 8

B)

ƒ(x) = 2x2 + 4x – 16

C)

ƒ(x) = 2x2 – 4x – 16

D)

ƒ(x) = x2 + 2x – 8

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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.
