Im new here so before asking my question, I'll introduce myself.
My name is jacob, I live in Flagstaff, Az. I frequently skii, and I run in cross country. (and track)
Anways, here is my question.
This is for function notation:
On one day the vlue of $1.00 U.S. was equivalent to 0.77 euro. On the same day $1.00 U.S. was equivalent to $1.24 Canadian. Write a function to represent the value of Cnadian dollars in euros. What is the value of the function for an input of 5 rounded to the nearest cent, and what does it represent?
Anways, I dont really get how to write that out, or how to get the output with 5 the input.
Same with this one:
PC Heaven sells computers at a 15% discount on the oriinal price plus a $200 rebate. Write a function to represent the final price of a computer at PC Haven. What is the value of the function for an iput of 2500, and what does it represent?
Also it says to graph these fuctions.
f(x) = x2 - 4. (the 2 is suppost to be a squard sign. Sorry I don't know how to do superscript online.)
I know you can do it somehow with slope intersept form, but I'm unsure how, to apply it to this.
Thank you vary, vary much!
