Question

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

Answer 1

Answer:

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

Answer:

f=√

3x−y

6dinx2

or f=−√

3x−y

6dinx2
