You can substitute 4 into this function to get an answer. The limit of the function f x should be defined at the point x a 3. Use integers or fractions for any numbers in the expression.

2 Taking the limit from the righthand side of the function towards a specific point exists. 𝑓 𝑥 𝑥 2 4 𝑥2 The denominator of this rational function should not be equal to zero that. By observing the given graph we come to know that.

Solution for Determine where the following function is continuous. 5 so lim_xrarr9fx5 and f9 5 so f is continuous at 9 f is continuous at every x greater than zero except 2 and 7. However there is a cusp point at 0 0 and the function is therefore non-differentiable at that point.

In order to determine if a function is continuous at a point three things must happen. Up to 10 cash back on the interval. For example you can show that the function.

Lim x- x0- f x f x 0 Because we have unfilled circle But lim x- x0 f x f x 0 Because we have the same unfilled circle at the same place Hence the given function is continuous at the point x x 0. Determine where the following function is continuous. The limit does not exist and the function is discontinuous at 7 At 9 we have equal one-sided limits.

Since left hand limit and right hand limit are equal for -2 it is continuous at x -2. Lim xa f x exists and equals f a. A Determine whether the following function is continuous at the origin.

This function shown below is defined for every value along the interval with the given conditions in fact it is defined for all real numbers and is therefore continuous. Hence the function is continuous for x R. Hence the function is continuous on the interval -3 3.
