Answer:

f(x) = x^3 + x^2 - 33x + 63

Step-by-step explanation:

The zeros are x = 3, x = 3, x = -7.

A polynomial function with zeros x1, x2, x3, ..., xn has the form:

f(x) = (x - x1)(x - x2)(x - x3) ... (x - xn)

The zeros of this function are 3, 3, -7.

The function is:

f(x) = (x - 3)(x - 3)(x - (-7))

f(x) = (x - 3)(x - 3)(x + 7)

Now we multiply out the right side.

f(x) = (x^2 - 6x + 9)(x + 7)

f(x) = x^3 + 7x^2 - 6x^2 - 42x + 9x + 63

f(x) = x^3 + x^2 - 33x + 63

Please helppp it’s confusing!!!

Answer:

First you'd look at PEMDAS (parenthesis, exponent, multiplication, division, addition, and subtraction( you'd look at them in this order to solve the equation properly.))

So there is a parenthesis, that would be the 3(2^0). ignore the three, because you're focusing on the parenthesis. Any number other than zero with an exponent of zero will always be one. leaving you with 3(1).

So by now you should know (depending on your level of mathematics, That a number beside a single number in a parenthesis is multiplication. so 3 times 1.

Knowing that any number, other than zero, multiplied by 1 is the number itself, The answer is 3

In short, 3(2^0) = 3

What is the vertex of the graph of f(x) = |x + 5| – 6?

Ket [755]

The vertex of the graph f(x)= lx+5l-6 is...
(-5,-6)
This is because of the picture above.

Hope this helps
