Which function has an inverse that is also a function? Can someone please help me with this problem?

The function that has an inverse that is also a function is .

Step-by-step explanation:

The only function whose inverse is also a function is the linear function, also named first-order polynomial. The inverse of a linear function is also a linear function. That is:

The function that has an inverse that is also a function is .

e) none of the above because the measure of angle cba is 101°

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
