Final answer:
To find f(1) for the given piecewise function f(x)={(x+1, for x>=0),(5x, for x<0):}, we use the first part of the function which is f(x) = x+1. Substituting x=1, we get f(1) = 2.
Step-by-step explanation:
To find f(1) for the given piecewise function f(x)={(x+1, for x>=0),(5x, for x<0):}, we need to determine which part of the function applies to x=1. Since x=1 is greater than or equal to 0, we use the first part of the function, which is f(x) = x+1. Substituting x=1, we get f(1) = 1+1 = 2.
