Question

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k.

k = _______

Answer 1

@ranga?

Answer 2

They don't give f(x) ?

Answer 3

it's the second line

Answer 4

Looking at the graph you can see g(x) is f(x) shifted up by 4 units. So what should k be in g(x) = f(x) + k?

Answer 5

i don't really know. Sorry i'm bad at math

Answer 6

k is the vertical translation of g(x)
take a look at the y-int of g(x) and y-int of f(x)
calculate the distance between this intercepts and that will be the value of k.

Answer 7

you're in high school, aren't you ?

Answer 8

can you help me on another question? And I'm home schooled

A State Park charges $5.00 per car plus $1.00 per person as an admission fee. The total charged for a car with x people is f(x) = x + 5. How will the graph of this function change if the per car charge is changed to $8.00 per car?

The line will shift vertically down by $3.00.

The line will shift vertically up by $3.00.

The line will shift vertically up by $8.00.

The line will shift vertically down by $8.00.

Answer 9

please help

Answer 10

same thing as you did from the graph..
since the value of per car is 5 then you will RAISE to 8, what will be the difference between these prices?

Answer 11

3?

Answer 12

yeah (^_^)

Answer 13

can you help me with another one?

Answer 14

i'll try though

Answer 17

???

Answer 18

negative 10 to 30, because these were the graphs starts and stops

Answer 19

okay @Data_LG2 can you help me with a few more?
A student is running a 5-kilometer race. He runs 1 kilometer every 3 minutes. Select the function that describes his distance from the finish line.

f(x) = - 1 over 3 x + 5

f(x) = - 1 over 5 x + 3

f(x) = 1 over 5 x + 5

f(x) = 1 over 3 x + 3
