(A) find F(x) for the indicated values of x, if possible

(B) find the domain of f.

F(x)=x^3 for x= -3, 5

(A) f(-3)

i do not know how to work the problem

A) The indicated values of F(x) for x=-3 and x=5 are  and

B) The domain of f is the set of all real numbers

Step-by-step explanation:

Given that the function F is defined by

for x=-3,5

A) To find F(x) for the indicated values of x :

Given for x=-3,5

Put x=-3 in the given function

Therefore

Put x=5 in the given function

Therefore

The indicated values of F(x) for x=-3 and x=5 are  and

B) To find the domain of f :

The domain of the f in the given expression is the set of all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

The domain of f is the set of all real numbers

The complete question in the attached figure

we know that
The length of the altitude to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse
h²=x*y
where
h is the length of the altitude to the hypotenuse
h=12
x and y are the two segments of the hypotenuse
so
12²=x*y----------> 144=x*y

the lengths of the two segments of the hypotenuse could be
x=6
y=24
x*y=144

the answer is
6 and 24
