*will give brainliest* function notation simply sets an expression equal to f(x), read "f of x," which means "f is a function of x." when given an equation in function notation, for example, f(x) = x2 − x + 1, you may be asked to do the following: evaluate the function for a given x-value—substitute the value for every x and simplify. interpret the solution or associated function statements. when given an equation in function notation, for example, f(x) = x + 1, you may be asked to do the following: solve for x given a function value—substitute the function value and solve for x. interpret the solution or associated function statements. when given a table or a graph, you may be asked to do the following: given an output value, identify the input value that corresponds. given an input value, identify the output value that corresponds. interpret what a solution or (input, output) means in the context of the problem.
