Well I don't know if I would recommend the blue I would actually would go for the yellow because it is my favorite color so ya she should pick yellow.
Present age of Justin=14
Present age of Sam=11
<u>Step-by-step explanation:</u>
Let the present age of Sam=x
Given that Justin is 3 years older than Sam
present age of Justin=x+3
Age of Sam 3 years ago=x-3
Age of Justin two years hence=x+3+2=x+5
given that after 2 years Justin's age will be twice that of Sam's age three years ago
therefore
Present age of Sam=x=11
Present age of Justin=x+3=11+3=14
See the attached figure.
<span>f(x)=-2x−3 ⇒⇒ black graph ⇒⇒ range = R
</span>
<span>g(x)=-2|x+3|−3 ⇒⇒ red graph ⇒⇒ range = </span><span>{y∣y ≤ -3}
</span>
<span>h(x)=-2(x−4)²+3 ⇒⇒ blue graph ⇒⇒ </span><span>range = {y∣y ≤ 3}
</span>
<span>j(x)=-2x³+3x²+x−1
⇒⇒ green graph </span>⇒⇒ range = R
∴ <span>
The function which has a range of {y∣y ≤ 3} is </span><span>
h(x)=-2(x−4)²+3
</span>
<span>
</span>
Which is the third choice<span>

If you used substitution to solve this equation, the answer would be (<span><span><span><span>76/21,</span></span></span></span><span>3/<span>7)</span></span>
