F(x)=-4x^2+7x+6 how do you work this
Ainat [17]

There actually isn't anything to 'work'.  There's no question there.

The function simply describes the relationship between two numbers.

It says that whatever you pick for the first number, the second number is

    (-4 times the square of the first one) plus (7 times the first one) plus (6) .

Your teacher may have assigned you something to do with the function,
like draw the graph of it, or find its maximum value (2.9375), or find where
it crosses the x-axis (2.381 and -0.63) or the y-axis (6).

But we can't tell what you've been assigned to do with it.  The function alone,
just as you've posted it, isn't asking a question, and doesn't call for any work.

3.) You just deposited $3,000 into a savings account with 3% annual interest. How much will you have in total after 2 years?​
Korvikt [17]

Answer:2,820

Step-by-step explanation:

multiply 3,000 by 0.03 which will get you 90 which is 3% of that for one year and for two years you just multiply 90 by 2 and get 180. subtract 180 from 3,000
