Answer:

Hello,

Step-by-step explanation:

Roots are -2 and 4

y=k*(x+2)(x-4)

Vertex = (1,-9) is a point of the parabola

-9=k*(1+2)(1-4) ==> k=1

Equation of the parabola is y=(x+2)(x-4)

But you don' t have given the graphs !!!!

If a polynomial function f(x) has roots 0, 3, and 2+ V5, what must also be a root of f(x)?

ddd [48]

Answer:

Option B.

Step-by-step explanation:

Note: Given roots are not in proper format.

Consider the polynomial function f(x) has roots 0, 3, and $2+\sqrt{15}$ .

According to irrational root theorem if $a+\sqrt{b}$ is root of a polynomial P(x), then $a-\sqrt{b}$ is also a root of polynomial P(x).

Since $2+\sqrt{15}$ is an irrational root of the function f(x). By irrational root theorem $2-\sqrt{15}$ is also a root of function f(x).

Therefore, the correct option is B.

Answer:

A four mile ride would cost $10

Step-by-step explanation:

Let T be the total ride cost

Let M be the amount of miles driven

T = 1.75M + 3

You can now sub in any distance in miles into the equation, but for this instance lets sub in 4 miles

T = 1.75*(4) + 3

T = 7 + 3

T = 10

Therefore, a four mile ride would cost 10 dollars
