If the function f(x)=mx+b has an inverse function, which statement must be true

The things we know that are true based on this is that m does not equal 0 and the inverse function is f(x) = .

We know that the slope is not 0, because there is no inverse function if this is the case.

Secondly, we can find the inverse function by switching f(x) and x and solving for the new f(x). The work for this is below.

f(x) = mx + b ----> switch f(x) and x

x = mf(x) + b ----> subtract b

x - b = mf(x) ----> divide by m

f(x) = .

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.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
