For this case we must find the value of the expression shown:

2 ^ {\sqrt {19}}

When entering in a calculator, we have the following:

\sqrt {19} = 4.35889894354

When rewriting the expression we have left:

2 ^ {4,35889894354} = 20,51914828

Rounding:

2 ^ {\sqrt {19}} = 20.5191

Answer:

if you horizontally strech the quadratic parent function, f(x)=x^2, by a factor of 4, what is the equation of the new function?
max2010maxim [7]

Answer:

     g(x) = x^2/16

Step-by-step explanation:

To stretch a function horizontally by a factor of k, replace x with x/k.

You want a stretch factor of 4, so your function is ...

  g(x) = f(x/4) = (x/4)^2

  g(x) = x^2/16

__

The attached graph shows the horizontal stretch.
