High School Calculus

[Savinelli]

I am quite horrible at calculus and need help with the class I am taking. I need any help I can get. If you can help send me a PM and I'll let you know the topics or send you the questions I have.

Any help would be amazing.

Just post your questions here.

 

[Savinelli]

1) Write the relation for the following table:
X 3 10 0 3 9 2
Y -1 4 0 7 -4 -5
2) Is the relation you created in #1 a function? Explain why or why not.
3) What is the domain of the following relation:
{(-2, 0), (3, 5), (6, 10), (9, 11)}
4) What is the range of the following relation:
{(-2, 0), (3, 5), (6, 10), (9, 11)}
5) What is f(-2) for f(x) = -1/2x+5

5) What is f(-2) for f(x) = -1/2x+5

1. (3,-10), (10,4), (0,0), (3,7), (9,4), (2,5)
2. No because it has an X value that is repeated [3]

5. f(x) = (-1/2)x+5 you subsitute the f(-2) into the equation where (-2) is X so you get (-1/2)(-2)+5 and you get 6
