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

1 answer:

3 0

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.

Please help it is 10th grade Equations of lines and circles 7. Michael is hanging out in the park and needs to keep his so

frosja888 [35]

Step-by-step explanation:

1) the required equation in common form is:

(x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates, where Michael is standing; r - the social distance;

According to the common form and given coordinates (x₀=-5; y₀=2; r=6) it is possible to make up the required equation:

(x+5)²+(y-2)²=6².

2) if the distance between two friends is:

$d=\sqrt{(-5-1)^2+(2-1)^2}=\sqrt{37}, \ then$

this distance is longer than social (6 ft). For more info see the attachment.
