Answer 1

for the first one just read off the values of g(x) corresponding to x = -5

Answer 2

i honestly dont know what to do exactly

Answer 3

llok at the column heading x and find -5
then read off the value next to it

Answer 4

so -2 and 0

Answer 5

this gives you the value of g(x) when x = -5
it is written as g(-5)

Answer 6

No just -2

Answer 7

oh ok so the final answer would be -2

Answer 8

for the first question Yes

Answer 9

For the second question

the function will be of the form
f(x) = nx + 5

because when x = 0, f(x) = 5 ( check the table)

f(x) = 0*n + 5 = 5

(0 times n = 0)

Answer 10

now need to find the value of n
we see from the table that f(x) = 8 when x = 1

so 8 = n + 5

can you solve this for n?

Answer 11

what number added to 5 gives you 8?

Answer 12

3

Answer 13

right

so it looks like the function is 3x + 5


lets check it out with the third row of the table
when x = 2 , f(x) = 11
so if we plug these values into f(x) = 3x + 5 we get

11 = 3* 2 + 5

is that correct? does 3*2 + 5 = 11?

Answer 14

This is the answer key
f(x)=x+5
f(x)=8x
f(x)=3x+5
f(x)=5x-3
