Help please math question

vlabodo [156]

Answer:

B

Step-by-step explanation:

To find the vertex of the parabola g(x), we expand (x+3)^2. So we get x^2+6x+9. Since the the x coordinate of the parabola is -b/2a, we plug it in. So we get -6/2 or -3. So x = -3 and y=0. So the answer is B. Shift down 3.

On a coordinate plane, a curved line with a minimum value of (negative 1.25, negative 3.25) and a maximum value of (0.25, negati

Juliette [100K]

The correct option is:

As the x-values go to positive infinity, the function's values go to positive infinity.

<h3>What is the end behavior of the function?</h3>

By the description, We know that the function has the points:

(-1.25, -3.25), (0.25, -1.75) (-2.25, 0), (0, -2), (-2.75, 6), (1.5, 6)

Notice that from x = 0.25 to x = 1.5 the function goes upwards, then in the right side, the function goes up, so as x goes to positive infinity, also does f(x).

On the left side, we can see that from x = -2.75 to x = -2.25 the function goes downwards.

So, as x goes to the left (negative infinity) f(x) goes upwards.

Then as x tends to negative infinity, f(x) tends to infinity.

The correct option is:

As the x-values go to positive infinity, the function's values go to positive infinity.

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial

Readme [11.4K]

Answer:

Result after multiplication of polynomial is: $6x^3+13x^2-5x$

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

$x(3x-1)(2x+5)$

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

$=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)$

Now multiplying with x

$= 6x^3+13x^2-5x$

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: $6x^3+13x^2-5x$

Degree of polynomial = 3
