: Please help me. I am trying to make corrections on homework from the last 2 weeks and am having trouble!
find values for each given function with the set of real numbers as the domain:
m(y)=y(1-2y) a. m(-1/2) b. m(1/2) c. m(0)
I have gotten that b. is zero and c. is zero, cannot get a.
thank you! This question is from textbook

m%28y%29=y%281-2y%29
a. m(-1/2)
m%28-1%2F2%29=%28-1%2F2%29%281-2%28-1%2F2%29%29 Substitute for y=-1/2
m%28-1%2F2%29=%28-1%2F2%29%281%2B1%29%29 Work from inside out and watch your multiplication (negative times negative equals positive)
m%28-1%2F2%29=%28-1%2F2%29%282%29%29 Simplify.
m%28-1%2F2%29=-1 Final answer.
