Can I get a check to see if these are right please?
1 answer:
The domain is all possible values for x.
Here we can see a parabola the goes sideways.
The vertex of the parabola is at (3,-1).
That means the domain is
Think about it this way, is there any point on the parabola that can have a x coordinate of 4?
The range of a function is all possible y values. Is seems that the parabola stretches infinitely up and down, meaning that all values of y are possible.

Answer: OPTION B.
Step-by-step explanation:
By definition, the slope equals the Rise divided by the Run; then, the slope can be found using the following formula:
Where "Rise" is the vertical change between two points and "Run" is the horizontal change between those two points.
In this case you can identify in the figure that:
Knowing these values, you can substitute them into the formula.
Through this procedure you get that the slope of the ramp is:
