Answer:
Fraction of the original board left =
Step-by-step explanation:
Let the length of the board is = l feet
Marty saws off of a wooden board.
Length of the board left = l -
= feet
He saws off of the remaining board,
Board left =
=
= feet
He finally saws off rd of the remaining board.
Board left =
=
= feet
Fraction of the original board left =
=
The x-intercepts of the piecewise function are 1.59 and 17 and the intervals where g(x) is positive are (-2,0) and [2,17)
<h3>The graph of the function</h3>The piecewise function is given as:
See attachment for the graph of the piecewise function.
<h3>The x-intercepts of the piecewise function</h3>This is the point where the piecewise function crosses the x-axis.
From the attached graph, the graph crosses the x-axis at x = -2, x = 0 and x = 17
Hence, the x-intercepts of the piecewise function are -2, 0 and 17
<h3>The intervals where g(x) is positive</h3>This is the range of x value where g(x) > 0
From the attached graph, g(x)> 0 between x = -2 & x = 0 and between x = 2 (inclusive) & x = 17
Hence, the intervals where g(x) is positive are (-2,0) and [2,17)
