function and domain c3 Watch
Study help in partnership with Birmingham City University
i dont understand how to find function and domain, do you just sub 0 into x and y and thats it? do you have to draw out graphs to find function and domain?
generally you should try and sketch the functions but just look our for common things like you cant have a negative root or a denominator that is 0 or an exponential function that is 0 or negative
how do you sketch the functions?
im still sorta lost
