Find each x-value at which f is discontinuous and for each x-value, determine whether f is continuous from the right, or from th

fredd [130]

Using continuity concepts, the answers are given by:

The function is right-continuous at x = 0.

The function is left-continuous at x = 1.

------------------------------------

A function f(x) is continuous at x = a if:

$\lim_{x \rightarrow a^{-}} f(x) = \lim_{x \rightarrow a^{+}} f(x) = f(a)$

If $\lim_{x \rightarrow a^{-}} f(x) = f(a)$ , the function is left-continuous.
If $\lim_{x \rightarrow a^{+}} f(x) = f(a)$ , the function is right-continuous.
For the given function, the continuity is tested at the points in which the definitions are changed, x = 0 and x = 1.

------------------------------------

At x = 0.

Approaching from the left, it is less than 0, thus:

$\lim_{x \rightarrow 0^-} f(x) = \lim_{x \rightarrow 0} x + 9 = 0 + 9 = 9$

Approaching from the right, it is more than 0, thus:

$\lim_{x \rightarrow 0^+} f(x) = \lim_{x \rightarrow 0} e^x = e^0 = 1$

The numeric value is:

$f(x) = e^0 = 1$

Since $[tex]\lim_{x \rightarrow 0^+} f(x) = f(0)$ , the function is right-continuous at x = 0.

------------------------------------

At x = 1.

$\lim_{x \rightarrow 1^-} f(x) = \lim_{x \rightarrow 1} e^x = e^1 = e$

$\lim_{x \rightarrow 1^+} f(x) = \lim_{x \rightarrow 1} 4 - x = 4 - x = 3$

$f(1) = e^1 = e$

Since $[tex]\lim_{x \rightarrow 1^-} f(x) = f(1)$ , the function is left-continuous at x = 0.

Write the ratio as a percent

sdas [7]

Answer:

68%

Step-by-step explanation:

Percent means out of 100, so lets see if we can change the fraction to have a denominator of 100

34/50 * 2/2 = 68/100

This is 68%
