Algebra.Com's Answer #571359 by josgarithmetic(39630)    ![]() You can put this solution on YOUR website! Read the points directly from the graph. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(A) You can find x=-2 on the x-axis. What is the function value at that x value?\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(B) You can find y=-4 on the y-axis. What are the x values which give or show this value for y, on the graph?\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "STILL MORE HELP WANTED\r \n" ); document.write( "\n" ); document.write( "The x-axis is the horizontal number line. \n" ); document.write( "The y-axis is the vertical number line.\r \n" ); document.write( "\n" ); document.write( "The function values correspond to the distance above or below the x axis for each value of x. f(x) means the value of the function or the y value, corresponding to the value of x. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The comments about (A) and (B) shown earlier are exactly what to do in order to answer the corresponding questions. This just cannot be made any simpler. I could directly tell you the answers to both, but the answers mean nothing if you do not understand ordered pairs and the idea of a function and its input.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Here is just an example, so you can follow it and compare to your questions. \n" ); document.write( "For which values of x does f(x)=3? \n" ); document.write( "ANSWER: At x=-1 and x=-5. \n" ); document.write( "  |
