<em>Greetings from Brasil...</em>

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

<em>A = ΔY/ΔX</em>

<em>B = where the line intersects the Y axis</em>

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

<h2>F(X) = 2X - 3</h2>

F(x)= √x-5. find f-2
rodikova [14]

For this case we have:

Be a function of the form y = f (x)

Where:

f (x) = \sqrt {x-5}

If we want to find f (-2), we substitute x = -2, then:

f (-2) = \sqrt {-2-5}\\f (-2) = \sqrt {-7}

Since we have a negative root, the result will be given by complex numbers. By definition:

\sqrt {-1} = i

So:

f (-2) = \sqrt {7} i

Answer:

f (-2) = \sqrt {7} i
