Interpretation :
The point
b)
To find : the distance between two given points.
b)

Answer to Problem 29E
The distance between given points is
Explanation of Solution
Given information : we have the given points are
Let the points be
We know that the distance between two points
Now, using the distance formula we get
Therefore, the distance between given points is

Note: f(x) = g(x). a) If_lim ƒ(x) = ∞ and_lim g(x) = ∞,then_lim [ƒ(x) − g(x)] = 0 x→ 0+ x→0+ x→0+ b) If h(x) and g(x) are continuous at x = c, and if h(c) > 0 and g(c) = 0, then h(x) lim. will = x→c g(x) c) If lim f(x) = 0 and lim g(x) = 0 then lim f(x) does not exist. x-a x-a x→a g(x)arrow_forwardPls help ASAParrow_forward
- 15. a) Consider f(x) = x-1 3x+2 and use the difference quotient to determine the simplified expression in terms of x, for the slope of any tangent to y = f(x). Also, determine the slope at x = 2. 15 b) Determine the equation of the tangent to f(x) at x = 2.
