Question

a g 6 ___ 8 ___ 10 ___ The number of grapes is 3 more than 2 times the number of apple slices in a fruit salad. Function: g = 2a + 3 Complete the table to show how the number of grapes, g, depends on the number of apple slices, a. Enter answers in order from top to bottom.

Answer 1

15

19

23

Explanation:

Substituting the number of apples given into our equation, we have

g = 2(6)+3 = 12+3 = 15

g = 2(8)+3 = 16+3 = 19

g = 2(10)+3 = 20+3 = 23

Answer 2

we are given

`g=2a+3`

where

g is number of grapes

a is number of apple slices

we can find different value of g at different values of 'a'

At a=6:

`g=2a+3`

we can plug a=6

`g=2*6+3`

`g=15`

At a=8:

`g=2a+3`

we can plug a=8

`g=2*8+3`

`g=19`

At a=10:

`g=2a+3`

we can plug a=10

`g=2*10+3`

`g=23`
