Answer:

A)  Function Rule: <u> y = x+3</u>

<u />

Substitution:

y = 2 + 3

y = 3 + 3

y = 4 + 3

y = 5 + 3

B) Function Rule: <u> y = 5x</u>

<u />

Substitution:

y = 5 * 2

y = 5 * 3

y = 5 * 5

y = 5 * 6

C) Function Rule: <u> y = x + (x - 1)</u>

<u />

Substitution:

y =  2 + (2 - 1)

y = 3 + (3 - 1)

y = 4 + (4 - 1)

y = 5 + (5-1)

Hope this helps! Tell me if you have any more questions!
