Question

Please Help!!! will medal and fan!!!

Answer 1

Use the four functions below (PICTURE INCLUDED) to compare and contrast these four functions using complete sentences. Focus on the slope and y-intercept first, and then on any additional properties of each function

Answer 2

f(x)=4x-3
j(x)=4x+3
h(x)=-4x+3
I believe g(x) might be -4x-3, as it appears they are varying the +/- symbols in each of them......I will check the g(x) in a second.

Answer 3

ok so the comare part is all of them have the slope of 4 or negative 4, and the y int is 3 or -3 but what is the difference?

Answer 4

yes, I believe I am correct on the g(x)

so the slope is negative whenever it has -4x in the front, and the y intercept is negative whenever you have -3.......they are all linear,

f(x) has positive interval from 3/4->infinity, and neg interval from neg infinity to 3/4, increasing interval from neg infinity to infinity

j(x) can never go below 0, as you cannot have negative hats, so it is positive y int pos slope and it has pos interval from 0->infinity, and interval of increase from 0->infinity

h(x) interval of decrease from neg infinity to pos infinity, always interval of decrease

g(x) interval of decrease from neg infinity to pos infinity, always interval of decrease

Answer 5

so positive 4x means positive slope and positive 3 means positive y intercept.

Answer 6

ok so the only difference is that the slopes and y intercepts have different signs?
