If g(x) =4x+2 and f(x) =3x-10 <br><br> find g(f(3))
Leya [2.2K]

Answer:

g(f(3))=-2

Step-by-step explanation:

So we have the two functions:

g(x)=4x+2\text{ and } f(x)=3x-10

And we want to find g(f(3)).

So, let's find f(3) first:

f(3)=3(3)-10

Multiply:

f(3)=9-10

Subtract:

f(3)=-1

Therefore, we can substitute -1 for f(3):

g(f(3))=g(-1)

Now, find g(-1):

g(-1)=4(-1)+2

Multiply:

g(-1)=-4+2

Add:

g(-1)=-2

And we're done!

So:

g(f(3))=-2

saul85 [17]

The coordinates of the vertex for the quadratic function are given as follows: (100,10).

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{b^2 - 4ac}{4a}

In this problem, the function is given as follows:

y = -x²/1000 + x/5

y = -0.001x² + 0.2x.

Hence the coefficients are a = -0.001, b = 0.2, c = 0 and the coordinates of the vertex are given as follows:

  • x_v = -\frac{0.2}{2(-0.001)} = 100
  • y_v = -\frac{(0.2)^2}{4(-0.001)} = 10
