WebGiven the function f (x) as defined above, evaluate the function at the following values: x = −1, x = 3, and x = 1. This function comes in pieces; hence, the name "piecewise" function. When I evaluate it at various x … WebSep 18, 2024 · On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So …
