Let the function f be defined by the equation y = f(x),
where x and
f(x)
are real numbers. Find the domain of the function. (Enter your answer using interval notation.)
f(x) = x3 − 5x + 3

Domain:  

Step-by-step explanation:

The domain of a function is all values of x such that f(x) exists.

In our case we have the following function:

We know that x and f(x) are real numbers, therefore the domain will be the interval , or in other words, the domain is all real numbers.

I hope it helps you!

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
