Y=2x+5. Fill in the table using this function rule.

Question

X 1
X 4
X 5
X 10

Answer 1

To fill in the table using the function rule, substitute each value of "x" into the equation "y = 2x + 5" to find the corresponding value of "y".

When x = 1:
y = 2(1) + 5
y = 2 + 5
y = 7

So when x = 1, y = 7.

When x = 4:
y = 2(4) + 5
y = 8 + 5
y = 13

So when x = 4, y = 13.

When x = 5:
y = 2(5) + 5
y = 10 + 5
y = 15

So when x = 5, y = 15.

When x = 10:
y = 2(10) + 5
y = 20 + 5
y = 25

So when x = 10, y = 25.

The completed table would be:

| x | y |
| --- | --- |
| 1 | 7 |
| 4 | 13 |
| 5 | 15 |
| 10 | 25 |
