Step-by-step explanation:

First, convert the mixed fraction into an improper fraction:

$1\dfrac{2}{5} = \dfrac{7}{5}$

Rewrite 2 as 2/1 and then cross-multiply to combine:

$\dfrac{2}{1} - \dfrac{7}{5} = \dfrac{(2)(5) - (7)(1)}{(1)(5)} = \dfrac{10 - 7}{5} = \dfrac{3}{5}$

How does the graph of y= -(2x+6)^2+3 compare to the graph of a parent function

raketka [301]

Here the list of the transformations applied to the parent function, and their effect:

$x^2 \to (2x)^2=4x^2$ . This causes a horizontal compression of factor 4.
$(2x)^2 \to (2x+6)^2= 4(x+3)^2$ . This causes a horizontal translation, 3 units to the left.
$(2x+6)^2 \to -(2x+6)^2$ . This causes a reflection about the x axis.
$-(2x+6)^2 \to -(2x+6)^2+3$ . This causes a vertical translation, 3 units up

So, if you start from the graph of $y=x^2$ , you have to compress and translate it horizontally, flip it with respect to the x axis, and finally move it up 3 units.
