Identify whether each of these functions contains a minimum or a maximum
[Title] Minimum Maximum
f(x)=7x2−49
f(x)=2x2−5x+1
f(x)=−12x2+4x−5
f(x)=−3x2+4x−7

f(x)=7x2−49 --> min

f(x)=2x2−5x+1 --> min

f(x)=−12x2+4x−5 --> max

f(x)=−3x2+4x−7 --> max

Step-by-step explanation:

If the coefficient of x² is:

Positive, it's minimum

Negative, it's maximum

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
