Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? Select three options. The domain is {x|x 5-2).
The range is {yly s 6).
The function is increasing over the interval (-00 ,-2).
The function is decreasing over the interval (-4, 00).
The function has a positive y-intercept.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

70

step-by-step explanation:

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.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
