Which is f(-3) for the quadratic function graphed ??

f(-3) = -9

Step-by-step explanation:

We want to find the value of the function when x = -3

f(-3) is the y value at x = -3

y = -9

f(-3) = -9

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
