Answer:
ok this is easy all it is 16-7=9 so a=9 so all it is 7x9=72 then its 72 divided by 2 so your answer is 36
Answer:
X->-infinite, graph is positive +(infinite)
X-> + infinite, graph is negative (-infinite)
Step-by-step explanation:
When you study end behaviour of a polynomial, you verify it's highest exponent. If it is odd, like this exercise, it's Y values come from negative infinity to positive infinity. If the coefficient is negative, it is the opposite, it comes from positive infinite to negative infinite.
1 + (-5) becomes 1 - 5 because you are adding a negative number.
1 - 5 is -4
