Describe the transformations of how the graph y=x^2 can be transformed into y= -1/5 (x-4)^2 + 2
Orlov [11]

Answer:

Reflected over the x-axis, vertically shrunk by a factor of 1/5, moved right 4 units and up 2 units.

Step-by-step explanation:

Parent Graph: f(x) = a(bx - h)² + k

<em>a </em>is vertical stretch (a > 1) or shrink (a < 1) and reflection over x-axis

<em>b</em> is horizontal stretch or shrink and reflection over y-axis

<em>h</em> is horizontal movement left (if positive) or right (if negative)

<em>k</em> is vertical movement up (if positive) or down (if negative)

Now that we have our rules, we simply apply it to y = -1/5(x - 4)² + 2

<em>a</em> = -1/5, so reflection over x-axis and vertical shrink of 1/5 (1/5 < 1)

Nothing has changed <em>b</em>, so no horizontal stretch/shrink

<em>h</em> = -4, so horizontal movement right 4 units

<em>k</em> = 2, so vertical movement up 2 units

How do you find a subtotal
jolli1 [7]

This is the hardest question I've answered all day.

One way to find a sub-total is by *simply* adding everything together, and a example would be below, buy yeah, you just add everything together.

For example:

Cookies (item # 594993) $2.98

Cake (item # 4354533) $4.50

Vans low tops (item # 594939) $60.00

Vans socks (item # 598993) $15.00

And just by adding all this, that how you would find the subtotal. Hope this helps! ;)
