Q. f(x)=⎩⎨⎧−3−6−2x−7 for for for x<−3x=−3x>−3 Find f(−8)Answer:
Identify Function Case: To find f(−8), we need to determine which part of the piecewise function applies when x=−8.The function f(x) is defined differently for three cases: when x < -3, when x=−3, and when x > -3.Since −8 is less than −3, we use the first case of the function, which is f(x)=−3.
Calculate f(−8): Now that we have identified the correct case, we can find the value of f(−8). According to the function, f(−8)=−3 because −8 falls into the range where x < -3.
