Rewrite the function to make it easy to graph using transformation of its parent function. Describe the graph. y = squ(25x - 25)
Mariana [72]
Parent function is y=√x
result is
-4+√(25(x-1))

-4 was added to whole function so translated 4 units down
it every x was multipied by 25  so horizontally stretched bya factor of 25
then, minus 1 from every x to move to right

so the blanks are
strech 25, 1 to the right, 4 down

What is the sales tax on a $8.50 purchase if the sales-tax rate is 6.5% (6 1/2 %)?
konstantin123 [22]
The answer is $0.55

$8.50 is 100%.
x is 6.5%

8.50 : 100% = x : 6.5%
x = 8.50 : 100% * 6.5%
x = 0.5525
x ≈ $0.55

Graph the equation.
omeli [17]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

Sometimes the quadratic is easier to graph if written in vertex form.

  y = -x^2 -6x -3

  = -(x^2 +6x) -3

  = -(x^2 +6x +9) -3 +9

  = -(x +3)^2 +6

This is a parabola that opens downward, with its vertex at (-3, 6). Unlike the one shown in the graph already, its scale factor is 1, so it will appear narrower than the one given with the problem statement.
