Find f(-9) when f(x) = |x|- 6.

f(x) = 3

Step-by-step explanation:

f(x) = |-9| - 6

f(x) = 9 - 6

f(x) = 3

3

Step-by-step explanation:

F(x)= f(-9) meaning x is -9.

When -9 is in absolute value is negative it turns into positive because anytime it it absolute it will turn any number postitive. so the equation turns into 9-6=f(x) which is 3.

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.

-1
