2. What needs do plants have that humans do not have? What needs do humans have that plants do not have?

Seeds and blood

Explanation: Plants need seeds to be planted and blood is self explanatory.

Plants need mineral rich soil to grow, humans do not need soil to grow. Humans need shelter, plants do not need shelter.

Explanation:

There are a lot of things that both plants and humans need, like sunlight, water, and food, but the ways we get these things and process them are very different. (We both need the sun, but plants need it to make food and we need it for vitamins. We both need food, but plants live off sugars and we need a variety of types of food.) There are also things that plants need and we don't, and visa versa.

what is the statement?

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
