Is it a function?

given the relation {(-4,-2),(1,-4),(3,0),(4,3)} determine if this relation is a function
a. yes it is a function because each x value has only one y value
b. no it is not a function because -4 appears twice
c. no it is not a function because each x value does not have a unique y value
d. yes it is a function because each x value is unique

by definition of a function:
a. yes it is a function because each x value has only one y value

Write (2-2i)^8 in the standard form a+bi

Find area of triangle: a=2,b=1,theta=100(degrees) <--the angle between them

Find dy/dx at the point (0, 1), if y^5 = (x + 2)^4 + e^xln y − 15 Amy.

Saying that 4 < sqrt(x) < 9 is equivalent to saying what about x?

typically we want to write inequalities in terms of a variable, so we rewrite it in terms of just x:

Find the GCF of the list.

We can successively divide out the gcf for each type of variable (as well as the coefficient). Each of them will be a factor for the entire gcf:

Find the arithmetic sequence such that the 12th term is 30and 22nd term is 50.
