A function is an algebraic formula that has a variable identified as its input and a calculation defined as its output that is dependent on the input variable.

a) f(2)={2^2}. 4
b) f(7)={7+10}. 17
c) f(0)={}. 0

f(x)=(x/4)-5

  1. A function calculates specific input and delivers one output to each input.

  2. a) f(2) = 2^2 = 4 b) f(7) = 7+10 = 17 c) f(0) = 0^0 = 0

  3. f(x) = {(x/4) - 5}

0^0 = 1, but the answer for c is 0^2 = 0.

#5096

Thanks for catching my error. You are correct. 0^0 could be 1 or it could be undefined, right? 0^2 = 0. That’s why I like to put my calculations in the answer, and not just show the answer. It helps me learn.

Thank you for getting back to me. I appreciate your time, but I’m still having a tough time understanding why I need to add 10 if 7 is an odd number.???

I have no background in this industry so most things are foreign to me.

Ill watch the video again to better understand the equation for question 2&3.
