    Transforming logarithmic graphs.

    Hi; I'm graphing -1/2log(base2)(-2x - 4)+3. I just want to confirm I'm entering this right into my graphing software, By having some points confirmed so for the parent function I have points (1,0)(2,1)(4,2) and (8,3) for the transformed function I have points...

    Transformations of graphs

    Question 1 The graph of the function y=e^x+10 is horizontally expanded by a factor of 6 and vertically expanded by a factor of 2. In terms of f(x) I know it would be y=2f(1/6x), but I am having problems plugging that into y=e^x+10. Question 2 The graph of the function y=x^3-7x is horizontally...

    graphing log vs t graphs help

    Hi, I have a question I need help with. The question is: Explain why, for an exponential model, the plot of logkv(t) versus t will result in a straight line of gradient equal to logk(b) and vertical intercept equal to logk(a). In the previous question, I had an equation of logkv(t) = logk(a)...

    Tables and graphs for "complicated word problems"

    As you may or may not know, I created two topics asking for assistance with complicated optimization problems (I have reposted both problems below for the sake of convenience). Thanks to the help of the experts on this forum, I acquired the answer for both problems, but I am now confronted with...

    Determining graphs

    Dominick graphs the equation y=a|x| where a is a positive integer. If Gina multiplies a by -3, the new graph will become 1) narrower and open downward 2) narrower and open upward 3) wider and open downward 4) wider and open upward

    Eigenvalues of complete partite Graphs.

    The eigenvalues of complete bipartite graph(Km,n) is given by the expression ±√m*n , 0(with multiplicity k-2). Where k is number of nodes in the graph. I am looking for generalization of the expression for eigenvalues of complete n-partite graphs. Does such a expression exists for complete...

    Graphing a compound inequality?

    So I really am a little confused about this, because every time I ask for help they give me a graph on a number line instead of a full scale x and y axis graph. Can I get some help please? Graph the compound inequality. 6x+2y>12 or x-6y<6

    Are these graphs Isomorphic?

    A. B. Determine if the pairs of graphs are isomorphic . For graph A I said they it is Isomorphic, but when I did the adjacency matrix it did not match up. For Graph B, I said it is not isomorphic but I could not find an invariant that is violated. Any help...

    Which graph or graphs appear to show a sinusoid?

    Which graph or graphs appear to show a sinusoid? A. ll only B. lll only C. l only D. l and ll only I think the answer would be D. l and ll only because III appears to be y=Floor(x) which is not sinusoidal. Is this right? Please explain answer. Thank you!

    natural log graphs

    Hi; what does the number 2 do in this function f(x) = -2ln(x - 5) - 3. I know the minus sign in front reflects the graph in the y-axis but I don't see what the 2 does?Thanks.
