B

royalranger · Answer

Where is the slope of the function negative?

mathmale · Answer

royalranger is correct.  You must be able to identify, from just looking at the graph, where the function is decreasing / where the slope of the tangent line to the graph is negative.

Think about this.  At what x value does the function start decreasing?  When does this decrease stop?  Write your answer as an INTERVAL, (a, b).  a and b are x-values.

kjsaif · Answer

Are the answers a and b?  The x value starts to decrease at -1
