<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:
gladly (:
Step-by-step explanation:
-4/5x+7=-13
multiply both sides of the equation by 5
-4x+35=-65
subtract 35 from both sides
-4x=-100
divide both sides of the equation by -4
x=25
The last one is the function
Answer:
x = 5
Step-by-step explanation:
9(x-2) = 3(x+4)
9x - 18 = 3x + 12
9x = 3x + 30
6x = 30
x = 5
