When x<span> approaches to </span><span>+∞</span><span> the function </span><span>e^<span>3x</span></span><span> becomes much bigger then </span><span>e^<span>−3x</span></span><span>, which obviously means that </span><span>e^<span>−3x</span></span><span> can be neglected in both numerator and denominator.
</span><span>
Here's how I figured this out:
</span><span>lim <span>x →+∞ </span></span>= (<span><span><span>e^(<span>3x))</span></span>− (<span>e^(<span>−3x)) / (</span></span></span><span><span>e^<span>3x)) </span></span>+ (<span>e^(<span>−3x)) </span></span></span></span>= <span>lim <span>x → +∞ </span></span><span><span>e^<span>3x / </span></span><span>e^<span>3x </span></span></span>= 1
The answer of the question is 125
Do 46.50 divided by 3. That gives you 15.5. Now do 15.5 multiplied by 4 because it says he deposited 3/4 of his paycheck.
The answer is 62.
(Sorry if there were any mistakes or if i read the question wrong) <span />
1. x=-2
2. y=-4x+1
3. not sure
The function has a minimum at (1,3) is the correct answer.
