Chapter 1: Q 17 (page 54)

Use a graphing utility to approximate the solutions of each equation rounded to two decimal places. All solutions lie between -10and 10.

x4-3=2x+1.

Short Answer

Expert verified

The required approximated solutions of the given equation are :-

-1.144and1.643.

Step by step solution

01

Step 1. Given Information 

We have given the following equation :-

x4-3=2x+1.

We have to solve this equation, by using graphic utility.

Firstly we will draw the two curves for left and right side expressions of the given equation.

The intersecting points of these curves will be the solution.

02

Step 2. Draw graphs

Given Equation is :-

x4-3=2x+1.

Let :-

Y1=x4-3andY2=2x+1

Now draw graph of both of these expressions on a single window using graphing utility as following :-

03

Step 3. Approximate Solutions 

In the following graph of given function :-

We know that solution exists, where both graphs cuts each other.

So the values of xfor that graphs cut each other, are the solutions of given equation.

So the approximate solutions of the given equation are :-

-1.144and1.643

Determine the coordinates of the points shown. Tell in which quadrant each point lies. Assume the coordinates are integers.

If two distinct lines have the same y

intercept, but different slopes, can they have the same x-intercept?

Find the midpoint of the line segment joining the points P1 and P2 .

P1=(3,-4);P2=(5,4)

The accepted symbol used to denote the slope of a line is the letter m. Investigate the origin of this symbolism. Begin by consulting a French dictionary and looking up the French word Monter. Write a brief essay on your findings.
