**Answer:**

cannot be determined from given information

**Step-by-step explanation:**

We are given information about one Gray whale and asked about Humpback whales. **No conclusion can be drawn**.

The domain is the x values that make the function defined. We can see the entire shaded region starts at x = 0 and goes on to infinity. The lines are solid and not dotted, which indicates 0 is included. That’s why answer D has a bracket in-front of zero

Option 4

**Answer:**

Easiest and fastest way to do this is to input both equations into a graphing calc and tracing to where the 2 graphs intersect.

Alternatively, you can use substitution to solve for your answer.

**Step-by-step explanation:**

**Answer:**

4x-10

**Step-by-step explanation:**

Multiply both by 2, 2x times 2 is 4x, and 5 times 2 is 10, so it becomes 4x-10.

To find the inverse, we swap the variables y and x, then solve for the new y.
