Answer:
Domain:
Range:
Step-by-step explanation:
<u>Domain</u>
We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write . Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.
<u>Range</u>
Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be .
A circle with center and radius
has equation
If we substitute in this equation, we have
This equation has two solutions (i.e. the line intersects the circle in two points) if and only if the determinant is greater than zero:
The expression simplifies to
The solutions to the associated equation are
So, the parabola is negative between the two solutions:
Answer: Probability of getting red both times is
Step-by-step explanation:
Since we have given that
A spinner is half red and half blue.
Probability of getting red is given by
Probability of getting blue is given by
Since he spins the spinner twice.
Probability that you will get red both times is given by
Hence, Probability of getting red both times is
