What is the initial value of the function f(x)=9(2/3)x+4?

Mathematics

Lynna [10]3 years ago
8 0

Answer:

x=-2/3

Step-by-step explanation:

f(x)=9×2/3x+4

0=9×2/3x+4(substitute f (x) =0)

0=9×2/3x+4

0=3×2x+4

0=6x+4

-6x=4( move the variable to left side and change the sign)

Divide both sides.. x=-2/3

The power generated by an electrical circuit (in watts) as a function of its current ccc (in amperes) is modeled by P(c)=-15c(c-
Paul [167]

Answer:

240

Step-by-step explanation:

The circuit's power is modeled by a quadratic function, whose graph is a parabola.

The maximum power is reached at the vertex.

So in order to find the maximum power, we need to find the vertex's y-coordinate.

We will start by finding the vertex's x-coordinate, and then plug that into P(c).

The vertex's x-coordinate is the average of the two zeros, so let's find those first.

-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.

Now let's take the zeros' average:

(0+8)/2=4.

The vertex's x-coordinate of this parabola is 4. Now let's find P(4).

P(4)=-15(4)(4-8)

240.

The maximum power of this circuit is 240 watts.

F(x) = 7x
ziro4ka [17]

The parent function is given by f(x)= 7x

and the transformation function is given by g(x)= 7x + 6

We can see that, 6 has been added to the function f(x) to get the function g(x).

We know that when we add some constant 'c' in the function then the function gets shifted upward by 'c' units.

Therefore, we will get g(x), when we will shift f(x) upward by 6 units.

Both functions are linear function hence, the asymptote of g(x) is the asymptote of f(x) shifted six units up.

D is the correct option.
