WebFeb 17, 2024 · Example 2: Finding Continuity on an Interval. Determine the interval on which the function f (x)= \frac {x-3} {x^2+ 2x} f (x) = x2+2xx−3 is continuous. Let’s take a look at the function above: First of all, this is a rational function which is continuous at every point in its domain. Secondly, the domain of this function is x \in \mathbb {R ... WebThe reason is because for a function the be differentiable at a certain point, then the left and right hand limits approaching that MUST be equal (to make the limit exist). For the absolute value function it's defined as: y = x when x >= 0. y = -x when x < 0. So obviously the left hand limit is -1 (as x -> 0), the right hand limit is 1 (as x ... WebFunction y = 2x 2 + 3Ax + B is continuous for for any values of A and B since it is a polynomial. Function y = 4 is continuous for x > 1 since it is a polynomial. Now determine A and B so that function f is continuous at x=-1 and x=1 . First, consider continuity at x=-1 . Function f must be defined at x=-1 , so i.) f(-1)= A(-1) - B = - A - B. in buddhist thought rebirth results from
