If the function f(x) = (2x - 3)2 is transformed to g(x) = (-2x - 3), which type of transformation occurred?

san4es73 [151]

Answer:

A. horizontal reflection

Step-by-step explanation:

Given:

$f(x)=(2x-3)^2$

$g(x)=(-2x-3)^2$

To identify the type of transformation.

Solution:

On close observation of the functions we find the that sign of $x$ has changed in $g(x)$ with other terms being constant.

Thus, the transformation statement can be given as:

$f(x)\rightarrow f(-x)$

As:

$f(x)=(2x-3)^2$

$f(-x)=(2(-x)-3)^2= (-2x-3)^2 = g(x)$

The transformation $f(x)\rightarrow f(-x)$ describes horizontal reflection of function across the y-axis.

Thus, $f(x)$ is horizontally reflected across y-axis to get $g(x)$ .

Mansa runs 1/3 of a mile in 1/16 of an hour. what is his unit rate in miles per hour

REY [17]

Answer:

5 1/3 mph or 5.33mph

Step-by-step explanation:

1/3 of a mile / 1/16 of an hour = MPH. In order to divide fractions you flip the bottom fraction and multiply across. 1/3 / 1/16 = 1/3 * 16/1 = 16/3 = 5 1/3 = 5.33mph

Alina [70]

Answer:

Step-by-step explanation:

$3x-5=9$

$3x-5+5=9+5$

$3x=14$

$\frac{3x}{3}=\frac{14}{3}$

$x=\frac{14}{3}$

x ≈ 4.66667
