Question

consider the piecewise defined functionevaluate this function at x=2. Express your answer as an integer or simplified fraction. if the function is undefined at any given value, indicate undefined.

Answer 1

f(2) = -9

Explanation:

Piecewise functions have different definitions depending on the value of x.

In this question, for values of x = 2 or lower, we have that:

f(x) = -x² - 2x - 1

So, evaluating the function at x = 2, we find f(2), that is, we replace each value of x by 2.

f(2) = -2² - 2*2 - 1 = -4 - 4 - 1 = -9
