P(P then C)=(7/10)(3/12)
P(PthenC)=21/120
P(PthenC)=7/40
Hey there!
A function is a relation to numbers in which an input value as a specific output value.
a) Is a function. All x values go to specific y values. For domain, look at the x values. You go from 2 to 8. So, 2≤x≤8 (we can assume the line just goes this long since we are not given anymore information) For the range, we have the same thing. It goes from 5 to 8. 5≤y≤8
b) Is not a function. 1 cannot go to two y-values.
c) Is not a function. Does not pass vertical line test.
d) Is a function. Passes the vertical line test. For the domain on this one, it would be infinite, which you could represent as (-∞,∞) It is infinite because the line as two arrows that continue forever. For the range, it would be anything greater than 2. y≥2 or 2≤y
The question stated you only needed to find the domain and range for the functions, so you would just do it for a) and d).
I hope this helps!

“Nerves that extend throughout the body on both sides emerging directly from brain and brain stem are called cranial nerves.”
Yes you are correct because it really is precise and delicate
Answer:
d. (-2, 5)
Step-by-step explanation:
Point T is reflected over the y-axis.
Therefore, the coordinates are (-2, 5).
