Which function's graph is shown below?
STALIN [3.7K]

Answer:

A. y = cos x

Step-by-step explanation:

The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.

Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.

If i have 2 1/2 pans of brownie left, and my sister eats 1/3 of the brownies, how much of a pan has she eaten
Tomtit [17]

Answer:

5/6 a pan of brownies.

Step-by-step explanation:

2 1/2=5/2, So you have 5/2 pans of brownies. If your sister eats 1/3 of these brownies we can write the equation 5/2*1/3=b=5/6, with variable b being how much of a pan of brownies your sister has eaten. Your sister has eaten 5/6 a pan of brownies.

A polynomial function has a root of -4 with multiplicity 4, a root of -1 with multiplicity 3, and a root of 5 with multiplicity
Ostrovityanka [42]

Using the Factor Theorem, the polynomial is given by: f(x) = (x + 4)^4(x + 1)^3(x - 6)^6

  • The graph is sketched at the end of the answer.

The <em>Factor Theorem</em> states that a polynomial function with roots x_1, x_2, \cdots, x_n is given by:

f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)

In which a is the leading coefficient.

In this problem, the roots are:

  • Root of -4 with multiplicity 4, hence x_1 = x_2 = x_3 + x_4 = -4.
  • Root of -1 with multiplicity 3, hence x_5 = x_6 = x_7 = 3.
  • Root of 5 with multiplicity 6, hence x_8 = x_9 = x_10 = x_11 = x_12 = x_13 = 6

Then:

f(x) = a(x - (-4))^4(x - (-1))^3(x-6)^6

f(x) = a(x + 4)^4(x + 1)^3(x - 6)^6

  • Positive leading coefficient, hence a = 1.
  • 13th degree, so it is odd.

Then:

f(x) = (x + 4)^4(x + 1)^3(x - 6)^6

At the end of the answer, an sketch of the graph is given.
