The graph of f(x), shown below, has the same shape as the graph of g(x) = 3x2, but it is shifted down 1 unit. what is its equation? f(x) = a. f(x) = 3(x + 1)2 b. f(x) = 3x2 + 1 c. f(x) = 3x2 - 1 d. f(x) = 3(x - 1)2

Step-by-step explanation:

We have been given the function , it is shifted down 1 unit. Now, whenever a function is shifted up or down we just the idea of vertical shift which says:

To shift a function up by 'k' units we use:

To shift a function down by 'k' units we use:

Here, in our case we have to shift the function down by 1 unit, so we will subtract 1 from the function:

So the required function is .

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

for future students the answer is b
