Question

a) Graph each function. b) State its domain and range. Write the domain and range in interval notation.

$\mathrm{f}\left(\mathrm{x}\right)=5.$

Short answer

Domain of linear function is$(-\infty ,\infty ).$Range of linear function is$\left\{5\right\}.$

Step-by-step solution

Step 1. Given Information

Given that the linear function equation is$\mathrm{f}\left(\mathrm{x}\right)=5$

Step 2. Linear function

It shows that as a constant function and slope is $\mathrm{m}=0.$The y-intercept is$(0,5).$

Step 3. Domain and range

Because given function is a constant linear function, domain of constant linear function is all real numbers. Domain of the constant functions is $(-\infty ,\infty ).$Because given function is a constant linear function, range of linear function is just a constant value. Range of the function is $\left\{5\right\}.$
