Algebra.Com's Answer #145296 by RAY100(1637)![]() ![]() ![]() You can put this solution on YOUR website! The most straightforward way to graph any function is to make a T box and plot the points. \n" ); document.write( "After much practice ,,,,you can recoqnize patterns,,,but this does work\r \n" ); document.write( "\n" ); document.write( "1) y=5x\r \n" ); document.write( "\n" ); document.write( "X,,,,,,Y \n" ); document.write( "______ \n" ); document.write( "0,,,,,0 \n" ); document.write( "1,,,,,5, ,,,,,,5*1=5 \n" ); document.write( "5,,,,25,,,,,,5*5=25\r \n" ); document.write( "\n" ); document.write( "it is linear,,,(no powers over x^1),,,, the y intercept is (0),,,, and the slope is (+5) \n" ); document.write( "remember,,,,y=mx+b,,,,with m=slope,,,,b=y intercept\r \n" ); document.write( "\n" ); document.write( "2) y=4x+2 \n" ); document.write( "X,,,,,,,,,Y \n" ); document.write( "0,,,,,,,,2 \n" ); document.write( "1,,,,,,,,6,,,,4(1)+2 \n" ); document.write( "-1/2,,,,0\r \n" ); document.write( "\n" ); document.write( "it is linear,,,,y intercept is (+2),,,,,and the slope is (+4)\r \n" ); document.write( "\n" ); document.write( "2)y=(1/3)x \n" ); document.write( "X,,,,,Y \n" ); document.write( "0,,,,0 \n" ); document.write( "3,,,,,1,,,,,,1/3 of 3 \n" ); document.write( "6,,,,,2,,,,,,1/3 of 6\r \n" ); document.write( "\n" ); document.write( "it is linear,,,,y intercept is 0,,,,,slope is +1/3\r \n" ); document.write( "\n" ); document.write( "4) y=log(5x) \n" ); document.write( "X,,,,,,,Y \n" ); document.write( "0,,,,,, (- infinity),,,,just use calc (5*0) log \n" ); document.write( "1/5,,,0,,,,calculator (1/5*5=1)log \n" ); document.write( "50,,,,2.4,,,calculator (5*50=250)log \n" ); document.write( "log functions all start at minus infinity at x=0, rise to y=0 at log (1), and then rise slowly,in our case to y=2.4 at x=(50) \n" ); document.write( " |
