For the function, f(x) = -5x 2, find f(-4).

Minchanka [31]

Answer:

The value of f(-4) = -80

Step-by-step explanation:

It is given that, f(x) = -5x²

<u>To find the value f(-4)</u>

Let f(x) = -5x²

To find the value of f(-4), substitute -4 instead of x

f(-4) = -5 * (-4)²

= -5 * 16 [ since (-4)² = -4 * -4 = 16 ]

= -80

Therefore the value of f(-4) = -80

Find the scale factor that was used to create the dilaton below

Ne4ueva [31]

Let:

$k\cdot IW=I^{\prime}W^{\prime}$

Where:

k = scale factor

IW = 12

I'W'= 8

so, solving for k:

$\begin{gathered} k=\frac{I^{\prime}W^{\prime}}{IW} \\ k=\frac{8}{12}=\frac{2}{3} \end{gathered}$
