Question

Express the rule in function notation for the statement subtract 1 and then square. (For example, the rule “square, then subtract 5” is expressed as the function $f\left(x\right)=x^2-5$.

Short answer

The rule in function notation is $f\left(x\right)={\left(x-1\right)}^2$.

Step-by-step solution

Step 1. Consider the real value function fx.

Let the function is $f\left(x\right)$in variable $\left(x\right)$.

Step 2. Apply the given statement of notation of function.

Subtract 1 from the variable$\left(x\right)$ and square the expression, so that the result obtained is $f\left(x\right)={\left(x-1\right)}^2$.

Step 3. Description of steps.

The required function is $f\left(x\right)={\left(x-1\right)}^2$.
