C) Basic unit of inheritance

Genes can be inherited by offspring from parent. They can determine a characteristic/trait, but usually many genes influence each. Genes can't be "measured" with a unit.

Let the graph of g be a horizontal shrink by a factor of 16 and a reflection in the x-axis, followed by a translation 2 units do

kifflom [539]

The graph of g(x) obtained from the horizontal shrink, reflection and translation of f(x) by a factor of 16, across the x–axis and 2 units downwards is given by the function;

g(x) = -(16•x)² - 2

Please see the attached graph of g(x)

<h3>What is a transformation of a function?</h3>

The transformation of the graph of a function is the shrinking, stretching, reflecting or translating of the graph of the function

The given function is f(x) = x²

The formula for reflecting a function f(x) across the x–axis to get g(x) is: g(x) = -f(x)

The formula for shrinking of a function f(x) horizontally by a factor of 16 is g(x) = f(16•x)

To translate the function, f(x), 2 units down gives; g(x) = f(x) - 2

The graph of g(x), which is a horizontal shrink by a factor of 16, a reflection across the x–axis and a vertical shift of 2 units downwards, is obtained from the function, g(x) = -f(16•x) - 2 = -(16•x)² - 2

Therefore;
