2. Given the following equations a. r + y = 15 b. x + 3y = 17 c. 2-y = 11 With justification, identify which one of the above relations is NOT a function? is a function that is NOT one to one? . is a one to one function? 3. A. Let f(r) = 2 x+5 g(a-h)-g(a) B. Let g(r) = r+3r x+5 Find a simplified formula for h 4. Using both interval and set notations, find the domain and range of the following functions: x+2 d. e(r) = 2 a. f(r)= b. g(x)= 1+x+2 1 c. h(x) = 3+= 1 12-1 Find a simplified formula for x + 7x+6 f(a+h)-f(a) h + -42 +3 2.
