Write the quadratic function f(x) = (3-x)2 in standard form.
Nitella [24]

Answer:

y =  - 2x + 6

Step-by-step explanation:

since \: f(x) = y \\

then the equation reads:

y = (3 - x)2 \\ y = 6 - 2x \\

The standard form of an quadratic function is:

y = mx + c \\

So the answer is:

y = mx + c \\ y =  - 2x + 6

Determine the slope from the given graph below:
Greeley [361]

Step-by-step explanation:

the slope is the ratio of "y coordinate difference / x coordinate difference".

so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.

(-1, -1) and (0, -7)

x changes by +1 (from -1 to 0).

y changes by -6 (from -1 to -7).

so, the slope is -6/1 = -6.

D is the right answer.

You have 45 1/3 pizzas for a party.  You have to split this 6 people per pizza.  How many people can eat? 

272 x 1/6 = 45 1/3

These three numbers can all be moved around.  With different functions, two of them will always equal the third.
