Activity 3. TRUE or FALSE. 1. The domain of the function \( f(x)=\frac{2 x+7}{x} \) is all real number except \( -\frac{?}{2} \) 2. The range of the function is the set of all values that \( f(x) \) will take. 3. In a rational function, the denominator must not be a zero function 4. The range of the function \( f(x)=\frac{5 x^{2}-6}{3 x^{3}} \) is all real number except \( \frac{5}{5} \). 5. The domain of the function is the set of all the values that the varia \( x \) can take or the set of values for which the function is defined.

Step 1
The function \( f(x) = \frac{2x+7}{x} \) is undefined when the denominator is zero. Set \( x = 0 \) to find the value that makes the denominator zero. Therefore, the domain is all real numbers except \( 0 \). The statement is FALSE. Show more…

Functions and Their Graphs
Determine whether each of the statements that follow is true or false. If a statement is true, explain why. If a statement is false, provide a counterexample. (a) True or False: Functions are the same as equations. (b) True or False: The domain of every function is a subset of $\mathbb{R}$. (c) True or False: The function that for each $x$ has output $f(x)=1$ is a one-to-one function. (d) True or False: Every global maximum of a function is also a local maximum. (e) True or False: Every local minimum of a function is also a global minimum. (f) True or False: The graph of a function can never cross one of its asymptotes. (g) True or False: Average rates of change can be thought of as slopes. (h) True or False: A function can have different average rates of change on different intervals.
