(Remember, x –b = 1 / x b.) Thus, power functions with negative exponents have no y-intercepts. Power functions with negative, whole number exponents like x –1 or x –2 are simple examples of rational functions, and for these functions x = 0 is an example of a singularity.
Now the integrand changes value from -1 to 1 at x = 0. Move the x slider and note the area on the left and the value of the accumulation function/antiderivative on the right. The antiderivative on the right changes from -1 to 1 at x = 0, because the area under the integrand graph switches from positive (above the x axis) to negative (below the ...

The factor (xLE2) has the value 1 for x <= 2 and 0 for x > 2. Similarly, (2Lx) is 1 for 2 < x and 0 otherwise. If we evaluate the sum above at x = 3, the first product is 0 because (xLE2) is 0 and the second product is (3 - 1)*1=2. In other words, for x > 2, the formula evaluates to x - 1.

Step-by-step explanation: The domain for x is all real numbers (without restrictions). For instance, if f (x) = x^2, on -5 < x < 5, on negative x, you must use f (x) = (-1)^2 to get 1. If x is >= 5, then the range is 3 - x, so f (x) = 3 - x, if x >= 5.
