Question

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?

f(x) = x + 4
x ,g(x)
−1, 8
1, 0
2 ,−4



The function f(x) has a higher y-intercept.

The function g(x) has a higher y-intercept.

They both have the same y-intercept.

The relationship between y-intercepts cannot be determined.

Answer 1

hi,
let;s take the function g(x)

in that function
when
x is -1 ----> y is 8
x is 1 ----> y is 0
x is 2 -----> y is -4

so... here when x increase the value for y decreases...
basically the shape of this graph is.....

and now let's take the function f(x)
in that function...
when x is -1....
f(x) = x + 4
= 3
when x is 1 ----> f(x) /y is 5
when x is 2 ----> y is 6

here
when x increases y also increases
so the shape of that graph is....


now wt can u say abt the y intercept of those 2 graphs ???

Answer 2

if we draw them in the same plane....

Answer 3

They are going in the opposite direction?

Answer 4

yep!!

Answer 5

and they intercept

Answer 6

so would it be The function f(x) has a higher y-intercept.

Answer 7

Ya got it riiight !!!

Answer 8

Woe! Thank you so much for the help! ^-^

Answer 9

U r welcome!!!
