Differentiate the function...

[samistumbo]

differentiate the function y=7e^x+(8/cuberoot(x))





Also... what's the answer to this one? f(x)=2^60
I thought I knew how to do it, but I keep getting the incorrect answer.... and I know this is an easy one.

Please show us what you tried, on each of these.

In general, we provide guidance, not answers.

Nevermind about the first one, I got it. 7e^x- 8/(3x^4/3)

The second one I got 118^59.... but it's not right.

what's the answer to this one? f(x)=2^60

This is a constant function.

Do they ask for f′(x) ?

This is a constant function.

Do they ask for f′(x) ?

yes

 

[mmm4444bot]

Have you learned yet that f′(x) is the slope of f(x) ?

What does the graph of y = 1152921504606846976 look like?

7e^x- 8/(3x^4/3)

\(\displaystyle \text{No, the exponent for x must have grouping symbols around it, }\)
\(\displaystyle \text{as well as the grouping symbols around the whole denominator, }\)
\(\displaystyle \text{such as:}\)


7e^x - 8/[3x^(4/3)] or


\(\displaystyle 7e^x \ - \ \dfrac{8}{3\bigg{x}^{\frac{4}{3}}}\)
