is the function of

Question

f(x)=x^2-4x

even, odd, or neither?

oh and on what intervals is the function of

f(x)=|x+1|+|x-1|

increasing?

Answer 1

for the first one, why not graph the parabola ?
hint: it has x-intercepts of (0,) and (4,0)

now check in your textbook or notebook what it says about even and odd functions in relation to their graphs.

for the second, I suggest you make a table of values, graph it, and draw your conclusion from that.
