Which quadratic function has a leading coefficient of 2 and a constant term of –3?
Romashka [77]
The answer is <span>f(x) = 2x2 + 3x – 3
</span>
f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term

<u>We are looking for a = 2, c = -3</u>

Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.

In the function: <span>f(x) = –3x2 – 3x + 2
</span>a = -3
c = 2

In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3

Change 3/5 to a percentage and a decimal
AURORKA [14]
A fraction is a short way to write a division problem.

Every fraction means  (the top number) divided by (the bottom number).

When you actually do the division, you get the decimal.

             3  divided by  5  =  0.60 .

To change any decimal to a percent, you move
the decimal point two places that way  ==> .

             0.60  =  60% .
