Answer:
Step-by-step explanation:
1. What are the x-intercepts of the graph representing f? They are the points on the horizontal axis where the graph touches or crosses the axis. Note that on this axis, y = 0.
2. What are the x- and y-coordinates of the vertex of the graph? Since the function is written as the product of two binomials, we can take these coordinates directly from the binomials: (x - 2) yields x = 2 and (x + 4) yields x = -4.
3. What is the y-intercept? Multiply out these binomials. We get:
f(x) = x^2 + 2 - 8. When x = 0, y = -8. The y-intercept is (0, -8).
20 pieces of wood left because....
if you need 7 nails for each piece of wood you have to determine how much wood you have by dividing the total amount of nails by 7 which would get you 60
420/7=60
if you already used 40 pieces then you have 20 left because..
60-40=20
