Given f(x)=3x-2x^2 find f(3)

Step-by-step explanation:

Let's solve for f.

y=3x−2x2findf(3)

Step 1: Flip the equation.

−6df2inx2+3x=y

Step 2: Add -3x to both sides.

−6df2inx2+3x+−3x=y+−3x

−6df2inx2=−3x+y

Step 3: Divide both sides by -6dinx^2.

−6df2inx2

−6dinx2

=

−3x+y

−6dinx2

f2=

3x−y

6dinx2

Step 4: Take square root.

f=√

3x−y

6dinx2

or f=−√

3x−y

6dinx2

f=√

3x−y

6dinx2

or f=−√

3x−y

6dinx2

where is the rest of the

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
