Answer:
Step-by-step explanation:
Tangent to y-axis means that the side of the circle TOUCHES the y axis.
Since the center is at (-7,2) and it touches the y axis, we can figure out the radius. It goes from (-7,2) to y-axis. Horizontally, the center is 7 units left of y-axis, so that is the radius ----- 7 units
The standard form of a circle is:
Where
(h,k) is the center
r is the radius
Putting the information into the form, we have:
THis is the standard form.

<h2>Q9. C.</h2><h2>Q10. B.</h2>
Step-by-step explanation:
Using continuity concepts, it is found that the correct options are:
- The function is continuous at x = -4.
- The function has an infinite discontinuity at x = -1.
-----------------------------
A function f(x) is continuous at x = a if:
-----------------------------
- At x = -4, there are no changes in the definition of the function, thus, it is continuous.
- At x = -1, we have that:
- A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.
