Did I pick the right answer?

C

Step-by-step explanation:

The domain of a function is the span of x-values.

And the range of a function is the span of y-values it covers.

From the graph, we can see that the span of x-values the graph covers goes from x=1 to x=6.

In other words, the domain is all numbers between 1 and 6 including 1 and 6.

In an inequality, this is:

For the range, we can see that the lowest the graph goes is y=1, and the highest it goes is y=7.

So, the range is all numbers in between 1 and 7 including 1 and 7.

In an inequality, this is:

Thus, the correct answer is C.

D is half correct, but the domain and range is flipped, so that may be your mistake. Be more careful next time!

step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
