Answer:
Not a function.
Step-by-step explanation:
The vertical line touches the graph at more than one point at once.
Answer:
t = 5
Step-by-step explanation:

Subtract 19 from 39
Divide by 4

The tangential line at a certain point is just the derivative so.

. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)
The tangential line at that point is
y - 6 = 2(x - 1) (this is the answer)
The answer is A the first choice
One-thousand five-hundred and sixty divided by twenty four is sixty five
