Question

Find a pair that the graph of $g$ is a horizontal stretch of the graph of $f$ .

$f (x) = \sqrt{x - 4}, g (x) = \sqrt{3 x - 4}$
$f (x) = x^{2} + 4, g (x) = 2 x^{2} + 8$
$f (x) = | x - 9 |, g (x) = \frac{3}{4} | x - 9 |$
$f (x) = x - 3, g (x) = 0.8 x - 3$

The correct answer is: $f left parenthesis x right parenthesis equals x minus 3 comma g left parenthesis x right parenthesis equals 0.8 x minus 3$

For horizontal stretch $g left parenthesis x right parenthesis equals f left parenthesis k x right parenthesis text for end text 0 less than k less than 1$
$g left parenthesis x right parenthesis equals 0.8 x minus 3 equals f left parenthesis 0.8 x right parenthesis$
$0 less than k equals 0.8 less than 1$
