number 5 the graph of the function f of x equals negative 1 + 5x is showing on the corner playing for what value of x does f of x equals 0 what we have here is a linear equation thing they put Apple vax which is false and function notation but I prefer them personally I prefer to use them Y intercept form slope intercept form so if it was me doing it I'm going to change that f of x to y  first off many kids are familiar with y equals MX plus b slope intercept form Y intercept form where m is the slope on go fishing X is the slope of a line in this case is .5 X  you can put it on .5 X or you can put as $45 a slogan for I want to run to from this point you rise one and you run to rise 1 Run 2 why the Rock and this case still slope the Y intercept the be here is -1 it crosses this line and egg so here we have negative one no my city for Equifax is the same thing as why right this is play the teachers at first and then they get fancy so using function notation and some people get fused but either way and its case f of x equal 0 if wine I forgot to the same like I'm telling you then you can simply sit in this y 0  now aware of f of x equals 0 will get X5 self so he will just answer break we we can add one  we have one of this play on the bolt size and we have 1/2 of X some number one half of some number on for my equal sign over here equals 1 half of what number equals 1 and basically half of 2 equals 1 can you cut a x - you could have divided by 1 Speedway 1/2 of 2 equals one so x equals two and we can see where x equals two it doesn't go up it does go down y equals 0 so x equals 2x of the first quarter why it was Zero it we certainly could what did the grassy realize that why was zero here if this is why we said change f of x to y y 0 we could see from the find the x intercept is where y equals 0 and the x intercept is to go over to Upper down so in this case correct answer is too and you could have done it visually the way I just ended up you could have done it whichever way what it's all good okay
