Let h(x) be a function defined by h(x) = -x3. a) Sketch the graph of h(x).
b) Find the inverse h-1(x) of h(x) then sketch the graph of h-1(x). c) Specify the domain and range of h(x) and h-1(x).
d) Determine the end behavior of h(x) and h-1(x).
3) When would the graph of a function cross the x-axis? Support your answer with details.

3 is greater then both of those numbers

the 3rd on is correct

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
