Question

State whether each equation or function is linear. Write yes or no. If no, explain your reasoning.

$5.h\left(x\right)=1.1-2x$

Short answer

Yes, the function $h\left(x\right)=1.1-2x$ is not 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 $f\left(x\right)=mx+b$, where $m$and $b$are real numbers

– Given information.

The given function is:

$h\left(x\right)=1.1-2x$

– Check whether the equation is linear or not.

The given function is in the form of $h\left(x\right)=mx+b$, where both $m=-2$and $b=1.1$are real values. So, the function $h\left(x\right)=1.1-2x$is a linear function.

Thus, the required answer is “Yes” because the function $h\left(x\right)=1.1-2x$is a linear function.
