Given f(x)=3x+12, find f(f^-1(0))
mamaluj [8]

Answer:

<h2>0</h2>

Step-by-step explanation:

METHOD 1.

We know:

f\bigg(f^{-1}(x)\bigg)=x

Therefore

f\bigg(f^{-1}(0)\bigg)=0

METHOD 2.

\text{Find}\ f^{-1}(x)

f(x)=3x+12\to y=3x+12

exchange x to y and vice versa:

x=3y+12

solve for y:

3y+12=x          <em>  subtract 12 from both sides</em>

3y=x-12        <em>divide both sides by 3</em>

y=\dfrac{x-12}{3}\to f^{-1}(x)=\dfrac{x-12}{3}

f\bigg(f^{-1}(x)\bigg)\to    replace x in f(x) with the expression\dfrac{x-12}{3}

f\bigg(f^{-1}(x)\bigg)=3\cdot\dfrac{x-12}{3}+12=x-12+12=x

f\bigg(f^{-1}(0)\bigg)\to put x = 0 to f\bigg(f^{-1}(x)\bigg)=x

f\bigg(f^{-1}(0)\bigg)=0

METHOD 3.

\text{Find}\ f^{-1}(x)

f^{-1}(x)=\dfrac{x-12}{3}

Calculate the value of <em>f</em> ⁻¹(x) for x = 0:

f^{-1}(0)=\dfrac{0-12}{3}=\dfrac{-12}{3}=-4

Calculate the value of <em>f(x)</em> for x = -4:

f(4)=3(-4)+12=-12+12=0

Answer:

D) a 360° clockwise rotation about the center of the parallelogram will take the parallelogram <em>PQRS </em> onto itself.

Step-by-step explanation:

The parallelogram <em>PQRS </em>is in quadrant III (3) of the coordinate plane.  If the image is reflected over the line x = -5 or y = -5, it would be the mirror image of itself and would move either left (x = -5) or down (y = -5) over the lines.  A 180°  rotation about the center of the parallelogram would move the object to quadrant I (1).  However, a 360° clockwise rotation about the center of the parallelogram would cause the object to make a full circle and take the  parallelogram <em>PQRS </em> onto itself.
