<span>Use the definition of continuity.
A function is continuous at a point x = a iff
lim [x → a] f(x) = f(a)
In other words, a function is continuous at a point if its value is equal to its limit at that point.
So, for f(x) to continuous at x = 4 we must have
lim f(x) = f(4)
x → 4

Answer:
P = -4
Step-by-step explanation:
Assuming that x = 20 and y = 24, you have to plug in these numbers for x and y to get to this equation P = 20 - 24. You should get -4 when you subtract 24 from 20 giving you a negative answer.
Well the X intercept is a coordinate point where there is a unique value to X coordinate, other than 0. Since the graph touches the X axis to the left of the graph, the X intercept would be negative. More specifically it would be (-3,0).
