Expert Solution

Answer to Problem 54E

The x-intercepts are 3 and 3andy-intercepts are 2 and 2 .

Explanation of Solution

Given information:

The equation x29+y24=1 and the graph of the equation is provided below,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 54E , additional homework tip  2

Formula used:

The x-intercepts are the points on x-axis where the graph of the equation intersects the x-axis.

The y-intercepts are the points on y-axis where the graph of the equation intersects the y-axis.

Calculation:

Consider the provided equation x29+y24=1 and the graph of the equation is sketched below,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 54E , additional homework tip  3

Observe from the graph that the curve intersects x-axis at two points 3 and 3alsoy-axis at two points 2 and 2 .

Recall that the x-intercepts are the points on x-axis where the graph of the equation intersects the x-axis.

Substitute y=0 in the equation x29+y24=1 ,

  x29+024=1x29=1x2=9x=±3

Therefore, x-intercepts are 3 and 3 .

Recall that the y-intercepts are the points on x-axis where the graph of the equation intersects the y-axis.

Substitute x=0 in the equation x29+y24=1 ,

  029+y24=1y24=1y2=4y=±2

Therefore, y-intercepts are 2 and 2 .

Thus, the x-intercepts are 3 and 3andy-intercepts are 2 and 2 .
