Nitella [24]

Answer:

a. 2

b. -1 or 2

Step-by-step explanation:

When the funtion h(x) is at 0, or h(0), the y value is visibly shown to be at 2. When the function's y-value is at -2, you need to find the x values which make that the case. You can see that at x=-1, the y value is at -2, making this our first value. You can also see the function meet -2 when x =2, making this the second value. Hope this helps!
