Chapter 1: Problem 28

Find the domain of each function. $$g(x)=\frac{\sqrt{x-3}}{x-6}$$

Short Answer

Expert verified
The domain of the function \(g(x)=\frac{\sqrt{x-3}}{x-6}\) is {x | x \(\geq\) 3 and x \(\neq\) 6}

Step by step solution

01

Set the Value Under the Square Root Greater than or Equal to Zero

Find the x-values that make x - 3 \(\geq\) 0. Solving this inequality leads to x \(\geq\) 3.
02

Determine the x-values that Make the Denominator Not Equal to Zero

Set the denominator of the function not equal to zero, then solve for x to find the x-values. This gives x \(\neq\) 6.
03

Find the Intersection of the Values from Step 1 and Step 2

The domain is the intersection of all x-values that satisfy both condition from step 1 and step 2. This gives us {x | x \(\geq\) 3 and x \(\neq\) 6}. This set notation expresses the domain of the function. The vertical bar | stands for 'such that'.

Here is the Federal Tax Rate Schedule \(X\) that specifies the tax owed by a single taxpayer for a recent year. (TABLE CANNOT COPY) The preceding tax table can be modeled by a piecewise function, where \(x\) represents the taxable income of a single taxpayer and \(T(x)\) is the tax owed: $$T(x)=\left\\{\begin{array}{ccc} 0.10 x & \text { if } & 0379,150 \end{array}\right.$$ Use this information to solve. Find and interpret \(T(20,000)\)

Graph both equations in the same rectangular coordinate system and find all points of intersection. Then show that these ordered pairs satisfy the equations. $$\begin{aligned}(x-3)^{2}+(y+1)^{2} &=9 \\\y &=x-1\end{aligned}$$
