Chapter 2: Q20. (page 66)

State whether each equation or function is linear. Write yes or no. If no, explain your reasoning.
$f (x) = 6 x - 19$

Short Answer

Expert verified

Yes, the function $f (x) = 6 x - 19$ is a linear function.

Step by step solution

– Definition of a linear equation and linear function.

In a linear equation the exponent of each variable is 1 and the variables may not be multiplied together. The graph of a linear equation is always a line.

In a linear function, each input value has a unique output value. In other words, for each point in domain, there is a unique value in the range of function. It can be written as $f (x) = m x + b$ , where m and b are real numbers.

– Given information.

The given function is:

$f (x) = 6 x - 19$

– Check whether the equation is linear or not.

The given function is in the form of $f (x) = m x + b$ , where both m=6 and b=-19 are real values. So, the function $f (x) = 6 x - 19$ is a linear function.

Thus,the required answer is “Yes” because the function $f (x) = 6 x - 19$ is a linear function.
