For the composition of two functions to be valid, the inner function must produce values within the domain of the outer function. Calculate and graph: \((f \circ g)(x)\) for \(f(x) = \sqrt{x}\) and \(g(x) = 2x-1\). The key idea is always to remember that the variable outside the parenthesis is the name of the function, while the variable inside the parenthesis is the input value of the function. They didn't tell me what the "units" are, but I know that volume involves cubed units, so my answer is: I usually think of plugging into formulas as plugging numbers into one side of the "equals" sign, and simplifying to find the value of whatever name (volume, surface area, arc length, etc) is on the other side. A further simplification would be: \[ h(x) = \pm 4(6-5x) = \pm (120-100x) \]. Begin with substituting the specified values and then find f(x) in each polynomial function presented in these easy and moderate levels of printable evaluating polynomial function handouts. But, to be on the safe side, I'll use them anyway, so I don't accidentally square the "minus" that comes before the variable. The result is also a function of x. Put the value of x in the outer function with the inside function then just simplify the function. So whenever you're There's no harm in using lots of parentheses, especially if you're just starting out. Direct link to nuha 's post like terms should ALWAYS , Posted 7 years ago.
