Using a minimum of two sentences, describe how to write the function, f(x) = (x + 2)^2 - 3, in standard form.

Lostsunrise [7]

First, simplify the (x+2)(x+2) with FOIL:
f(x)=( $x^{2} +2x+2x+4$ )-3
Combine like terms
f(x)= $x^{2} +4x+1$
Then you have standard form.

Hope that helps.

What is the value for f(x)= 3^2x+1 when x =1/2

Papessa [141]

Taking 2x is power of 3.

So it will be like 3^(2*1/2) + 1
You are replacing 'x' with 1/2
and the equation becomes 3^1+1
So, f(1/2) = 4
Answer is 4.

If its like
<span>3^(2x+1)
Then its like 3^[(2*1/2) +1]
It becomes 3^(1+1) = 3^2 = 9
So, the answer is 9
