Studdy Solution

STEP 1

Assumptions1. The function is defined piecewise, with three different expressions for different ranges of x. . The function is continuous within its defined intervals.
3. The function is defined for all real numbers.

STEP 2

We will graph each piece of the function separately. Let's start with the first piece, f(x)=4f(x) =4 for x1x \leq -1. This is a horizontal line at y=4y =4 for x1x \leq -1.

STEP 3

To graph this piece, we plot a point at (1,)(-1,) and draw a horizontal line to the left of this point. The point at (1,)(-1,) should be a filled circle because the function is defined at x=1x = -1.

STEP 4

Next, we graph the second piece of the function, f(x)=x+3f(x) = x +3 for 1<x<4-1 < x <4. This is a linear function with slope1 and y-intercept3.

STEP 5

To graph this piece, we plot points at (1,2)(-1,2) and (4,7)(4,7) and draw a line through these points. The points at (1,2)(-1,2) and (4,7)(4,7) should be open circles because the function is not defined at x=1x = -1 and x=4x =4.

STEP 6

Finally, we graph the third piece of the function, f(x)=2x2f(x) =2x -2 for x4x \geq4. This is a linear function with slope2 and y-intercept -2.

STEP 7

To graph this piece, we plot a point at (4,6)(4,6) and draw a line with slope2 to the right of this point. The point at (4,6)(4,6) should be a filled circle because the function is defined at x=4x =4.

STEP 8

By combining the three pieces, we obtain the graph of the function f(x)f(x).
