Hi grandma, at school today I learned about the attributes of functions.
Ah yes ! I remember learning that back in the old days.
We can use the function f (x)= 2x^2 -1 as an example . First we can find the domain. The domain is all real numbers. As for the range would be [-1, infinity)
I see !
To find the x intercept you make f(x)=0 then move variable, divide, simplify , then separate solutions.
So x would be
To find the y intercept you make x=0 , evaluate, calculate , then remove 0
So y would be (0,1) right ?
To find if the fuction is even or odd use substitution, determine the sign , then use substitution.
So it would be an even function !
The aos would be the line that cuts the function in two halves
And the max would be the highest point and the min would be the lowest point .
