Part 2 (matlab) Functions Many of you will have some form of a loan during your lifetime, either a student loan, mortgage, credit card debt, or other loan. If you never do have a loan, great! But you may have to calculate a payment for someone else, such as the company you work for. Such a loan will have a principal amount (called the present value), an interest rate, and a number of periods for the loan. The formula to...

Let f(x) = x*(2-x) if x>=0, or x*(x+2) if x<0 i) graph the function from x=-3 to x=+3. If you like WolframAlpha, use Piecewise[{{x*(2-x),x=>0},{x*(x+2),x<0}}] If you like Desmos, use f(x)= {x>=0:x*(2-x), x<0:x*(x+2)} (for some reason, when you paste that it, it forgets the first curly-brace { so you’ll need to add it in by hand) Or, you can use this, but it makes it less clear how to take the derivative: f(x) = -sign(x)*x*(x - 2*sign(x) ) ii) Find and...

New research on the effects of social media usage has been mixed. Some studies have found that social media helps people stay connected to others, and can be a positive source of social support. Other studies have found that social media makes people feel lonely and unhappy. I decide to do my own study to see whether social media has an effect on how many close friends people have. I conduct an internet survey of 1000 people and ask them...
