Estimate the x-coordinates at which the relative maxima and relative minima occur for the function. f(x) = 3x3 + 9x2 – 1

ANSWER

Relative minimum occurs at x=0

Relative maximum occurs at x=-2

EXPLANATION

The given function is;

We take the first derivative to get:

At turning point f'(x)=0

We take the second derivative to get

Relative minimum occurs at x=0

Relative maximum occurs at x=-2

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

$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
