Question

Express the function$k\left(x\right)=\frac{x^2-4}{3}$ in words.

Short answer

Subtract 4 from the square of input variable$\left(x\right)$ and divide by 3.

Step-by-step solution

Step 1. Convert machine input of x2−4 into words.

From $k\left(x\right)=\frac{x^2-4}{3}$, subtract 4 from the square of input variable $\left(x\right)$.

Step 2. Convert machine input of x2−4 divided by 3 into words.

From the function$x^2-4$ is divided by 3 after subtracting 4 from the square of input variable $\left(x\right)$.

Step 3. Description of steps.

Hence, the function in word notation is subtract 4 from the square of input variable$\left(x\right)$ and divide by 3.
