1. if f(x)=3x-1, find f(-5)

2. if h(x)=2x+3 and g(x)=3-4x, find 3h(1)-g(2)

1 f(-5) = 3(-5)-1= – 15 – 1 = – 16

2. h(1) = 2(1)+3=2+3=5

g(2)= 3- 4(2)=3 – 8 = – 5

3h(1) ‐ g(2) = 3 (5) – (-5) = 15 +5= 20

I hope I helped you^_^

1.true 2.false? ? i think. .

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.
