How does the graph of the function f(x)=2x^3-1 differ from the graph of its parent function?

Graph of parent function stretch vertically by factor 2 and shifts 1 units down to get the graph of f(x).

Step-by-step explanation:

The given function is

Its parent function is  

The translation is defined as

               ... (1)

Where, k is stretch factor, a is horizontal shift and b is vertical shift.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The given function can be written as  

        ...(2)

On comparing (1) and (2), we get

It means graph of parent function stretch vertically by factor 2 and shifts 1 units down to get the graph of f(x).

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
