Find the x-intercepts. state whether the graph crosses the x-axis or touches the x-axis and turns around at each intercept. show your work.

f(x) = x2(x + 2)

The x-intercepts will be at x = 0 , -2

Step-by-step explanation:

Given

f(x) = x²(x+2)

To find the x-intercepts ⇒ f(x) = 0

∴ x²(x+2) = 0

∴ x² = 0  OR   x+ 2 = 0

∴ x = 0  or   x = -2

So, the x-intercepts will be at x = 0 , -2

To figure out whether the graph crosses the x-axis or touches the x-axis and turns around at each intercept, we need to graph the function f(x)

The attached figure represents the graph of f(x)

As shown in the figure:

1)  The graph crosses the x-axis at x = -2

2) The graph touches the x-axis and turns around at x = 0

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

well, if it's triangular garden, the triangle could represent the garden.
