Math Problem Statement

What are the x- and y-intercepts of the graph of the function based on the given table of values?

Solution

The table in the image represents the values of a linear function. We are tasked with finding the x- and y-intercepts of the function based on the data provided.

The x-values and corresponding y-values are:

  • x=3x = -3, F(x)=10F(x) = 10
  • x=1x = -1, F(x)=3F(x) = -3
  • x=1x = 1, F(x)=2F(x) = -2
  • x=3x = 3, F(x)=2F(x) = 2

To find the x- and y-intercepts, we first need to determine the equation of the line that fits these points.

Steps:

  1. Find the slope of the line (m): The formula for slope is: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Using two points from the table, for example, (3,10)(-3, 10) and (1,3)(-1, -3): m=3101(3)=132=132m = \frac{-3 - 10}{-1 - (-3)} = \frac{-13}{2} = -\frac{13}{2}

  2. Find the equation of the line: Using the point-slope form of the equation of a line: yy1=m(xx1)y - y_1 = m(x - x_1) Using the point (3,10)(-3, 10) and the slope m=132m = -\frac{13}{2}: y10=132(x+3)y - 10 = -\frac{13}{2}(x + 3) Simplifying this equation will give the equation of the line.

  3. Find the y-intercept (b): Set x=0x = 0 and solve for yy. This will give the y-intercept.

  4. Find the x-intercept: Set y=0y = 0 and solve for xx. This will give the x-intercept.

Let's proceed with the calculations to determine the intercepts.
