Question

Fill in the table using this function rule

y=-4x+3
x y
-1 =
0=
1=
2=

Answer 1

This one isn't too hard, just plug in each value!

x = -1
y = -4(-1) + 3
y = 7

x = 0
y = -4(0) + 3
y = 3

x = 1
y = -4(1) + 3
y = -1

x = 2
y = -4(2) + 3
y = -5

Answer 2

1st blank: 7

2nd blank: 3

3rd blank:
`-1`.

4th blank:
`-5`.

Explanation:

We have been given a function formula
`y=-4x+3`. We are asked to fill in the given table.

We will substitute the given x values in our given formula to solve for y as:

`y=-4x+3`

`y=-4(-1)+3`

`y=4+3`

`y=7`

1st blank: 7

`y=-4x+3`

`y=-4(0)+3`

`y=0+3`

`y=3`

2nd blank: 3

`y=-4x+3`

`y=-4(1)+3`

`y=-4+3`

`y=-1`

3rd blank:
`-1`

`y=-4x+3`

`y=-4(2)+3`

`y=-8+3`

`y=-15`

4th blank:
`-5`.
