So we’ve got the function ( f(x) = (2x^3 + 5x^2 - 7)^{88} ) and we want to find the derivative of our function ( f ) with respect to ( x ). Now, the key here is to realize that this function can be viewed as a composition of two functions. How do we do th…

All right, we have a graph of ( y ) is equal to ( f(x) ), and we want to figure out what is the limit of ( f(x) ) as ( x ) approaches negative three. If we just look at ( x = -3 ), it’s really hard to see, at least based on how this graph looks, what ( f(…
