Answer:
(8.5)
Step-by-step explanation:
Just add the 2 numbers
The answer would be: 17/4
If <em>x</em> = -1, you have
2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0
and if <em>x</em> = 0, you have
2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0
The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
No but there's a website where you can calculate what grade you need in order to get a certain grade in the class. Just add the extra credit grade to the grade you have first.
Also, it's extra credit. Why wouldn't you do it? It's FREE points (sort of).
