3. Write two linear functions, fx) and g(x). For example, f(x) = 3x - 7 and g(x) = -2x+ 5. Then see whether f(x) - (-9(x)) is equivalent to f(x)+ g(x). Hint:
To find -g(x), just change the signs of all the terms in g(x). Discuss whether
you think your results would apply to every function.

What is the binomial expansion of (2x-3)^5

Each month, a shopkeeper spends 5x + 14 dollars on rent and electricity. if he spends 3x−5 dollars on rent, how much does he spend on electricity? for which value(s) of x is the amount the shopkeeper spends on electricity less than $100? explain how you found the value(s).
