How are the zeros of a polynomial function used to create a graph

Answers

Answer 1
Answer: 11 . Predict the end behavior of the function.

22 . Find the real zeros of the function. Check whether it is possible to rewrite the function in factored form to find the zeros. Otherwise, use Descartes' rule of signs to identify the possible number of real zeros.

33 . Make a table of values to find several points.

44 . Plot the points and draw a smooth continuous curve to connect the points.

55 . Make sure that the graph follows the end behavior as found in the above step.

What is the probability that a randomly selected candle is orange scented? Story: A factory produces 8000 candles each day. They produce equal quantities of cherry, lemon, orange and strawberry. The candles are mixed together during packaging.

Answers

Since the factory produces equal numbers of 4 types of candles, we can find the number of candles it produces of any given type:


We have found that the factory produces 2000 candles of each type. Since the probability of something happening is the number of favored outcomes divided by the number of total outcomes, we can find the probability of an orange scented candle being chosen are:


The answer is 1/4.

Let f(x) = x to the second power − 8x + 5. Find f(−1).

Answers

Hello!

To find the value of f(-1), you need to substitute -1 into each x variable and solve. Remember to use PEMDAS when simplifying.

f(x) = x² - 8x + 5 (substitute -1 for x)

f(-1) = (-1)² - 8(-1) + 5 (simplify the exponent)

f(-1) = 1 - 8(-1) + 5 (multiply)

f(-1) = 1 + 8 + 5 (add alike terms)

f(-1) = 14

Therefore, the value of f(-1) is 14.
