The domain of the graph is less than or equal to 0.
Answer: y=−5/4x−5
Step-by-step explanation:
Three tenths is the same as 3/10
the sum of -2 and -28 is -30
3/10 of -30 is the same as the products of the two
3 x -30 / 10 = -90/10 = -9
Your answer is
3(-2 + -28)/10 = -9
If
then complex number
is a root of cubic polynomial.
If polynomial has real coefficients, then conjugated
is also a root of polynomial.
Then the polynomial will be of a form

Since
then

Therefore,
