F(x) = x²-x
g(x) =1/x
1) h(x) =f(x) -g(x) = (x²-x) - (1/x) = (x³-x²)/x (x≠0) =>
2)h(x) =f(x).g(x) = (x²-x).(1/x) =x(x²-1)
3)h(x) = f(g(x)) = (1/x)²-(1/x)
2nd one, please correct me if i’m wrong .
Answer:
In the word neuroplasticity, the prefix, neuro-, refers to the brain. The suffix, plasticity, refers to malleability or the ability to change. Thus, neuroplasticity refers to the ability of the brain to change. It's important to note that until the mid-20th century it was believed that after childhood the human brain was unchangeable and couldn't respond to external circumstances. However, it's now known that the brain continues to change throughout life.
