Question 709128: Please help me solve these equations please! Thank you!
Let f(x)= 2x+3 and g(x)=x^2-x Find Each Value

Problem 1: (f+g)(1/2)

Problem 2: (f*g)(1)

Problem 3:(f/g)(2)

Problem 4: (f of g) (5)

Using just #3 as an example:

You want the function which is the ratio of f to g, and then evaluate at x=2.

and for x=2, evaluate this:

and you can finish that.

Problem #4 is composition of functions. g(x) is used as input to f(x), and the result is to be evaluated at x=5.

f(g(x))=2()+3,.... not finished. We want to put g(x) into the missing parentheses position...

= --------we could use either form of the function.
NOW use x=5 and evaluate f(g(5)).
