The graph represents function 1 and the equation represents function 2: A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3. Function 2 y = 3x + 1 How much more is the rate of change of function 2 than the rate of change of function 1? 1 2 3 4

im not acctually typing, it just says that.

Look at the graph of Funtion1 It is a straight line, what is its slope ?
Joehoffy
  • Joehoffy
its a straight line and its constant
ganeshie8
  • ganeshie8
Good observation. The line is flat, not changing.
ganeshie8
  • ganeshie8
What is the slope of a flat line ?
Joehoffy
  • Joehoffy
The slope of a horizontal line is 0!
ganeshie8
  • ganeshie8
Very good !
ganeshie8
  • ganeshie8
so the rate of change of function1 is 0
ganeshie8
  • ganeshie8
Look at Function2 they gave you an equation of a straight line. do you know how to find the slope when an equation is given ?
Joehoffy
  • Joehoffy
i guess.
ganeshie8
  • ganeshie8
When you make an educated guess, the chances are more for it to be a correct guess... so what is your guess ?
Joehoffy
  • Joehoffy
2?
ganeshie8
  • ganeshie8
why 2 ?

i dont really know, is this going to be of any help: https://www.google.com/search?q=y+%3D+3x+%2B+1&oq=y+%3D+3x+%2B+1&aqs=chrome..69i57j69i64&sourceid=chrome&es_sm=93&ie=UTF-8?

if i guessed, how would i know why lol? i dont know how to do this, its really puzzling/

  • Joehoffy
wow... umm.... whats that?
ganeshie8
  • ganeshie8
I have graphed part of the equation. Stare at the graph - When you go right by 1 unit, how much is the grpah rising up ?
Joehoffy
  • Joehoffy
0
ganeshie8
  • ganeshie8
|dw:1449320645104:dw|
ganeshie8
  • ganeshie8
Observe that the graph is rising up by 3 units for every one unit to the right
ganeshie8
  • ganeshie8
Now make a guess again, whats the slope of that red line ?
Joehoffy
  • Joehoffy
3
ganeshie8
  • ganeshie8
Yes!
Joehoffy
  • Joehoffy
omg THANK YOU! i get it now.
ganeshie8
  • ganeshie8
slope = rise / run = 3 / 1 = 3
ganeshie8
  • ganeshie8
Now that you have rate of change for both the functions, see if you can answer the given question
ganeshie8
  • ganeshie8
np, may i know your final answer
Joehoffy
  • Joehoffy
oh wait... is it 1 or 3? hmmmmmm
Joehoffy
  • Joehoffy
its 1 right?
Joehoffy
  • Joehoffy
i think so.... *facedesk*
ganeshie8
  • ganeshie8
rate of change of function1 is \(\color{blue}{0}\) rate of change of function2 is \(\color{blue}{3}\) whats the difference ?
Joehoffy

Joehoffy
  • Joehoffy
ok so why was i so confused wth??
Joehoffy
  • Joehoffy
*facepalm**facepalm**facepalm**facepalm**facepalm**facepalm**facepalm*
ganeshie8
  • ganeshie8
you aren't confused, it takes time to understand these... good to see you are taking time to digest these instead of simply giving up !
Joehoffy
  • Joehoffy
thank you :P
