Hw#51: As you complete these problems, label them using the 3-digit number at the end of the link. For example, the first problem below is 624.
Hint for 624: A function is a rule mapping an input to an output, but an input cannot have two outputs for the same input. Two different inputs can have the same output though.

Hint for 630: f(-4)=10 means that when x=-4, y=10. What coordinate point represents that? If you are having trouble with part b, know that for part a, I can say that -4 is a solution for f(x)=10.
Hint for 599: Choose an example “parent function,” f(x) = ____, and then think about f(x+h) and f(x)+f(h).
Hint for 649: Note the scale of each graph. They are not all the same!
Hint for 640: What is a reasonable vertex? What are reasonable x-intercepts? What direction is the parabola opening up in? Which function matches those answers? Remember: y=(x-a)(x-b) tells you (a,0) and (b,0) are x-intercepts. y=(x-h)^2+k tells you that (h, k) is the vertex. When you multiply it out, is the leading coefficient negative or positive?
Hint for 375: The height of the springboard is the height that the diver starts at.

Graph (use a table of values, plot example points): y=x^3; y=x^1/2; y= x^1/3; y=log(x)
