Best ResponseYou've already chosen the best response.0im trying to find the x intercept of the unknown line, not f(x)=10^x

Best ResponseYou've already chosen the best response.0@emilyoo in any question intercept means the point of intersection with the respective ... In this case you want the x intercept of l... the equation of l is \[10^{x}\] Now for what value of x will will i be zero... Now apply limit to the function of yuors and solve it for infinity This will give you the x intercept of the curve...

Best ResponseYou've already chosen the best response.0So first find the equation of the line

Best ResponseYou've already chosen the best response.0@emilyoo Does the line and the curve intersect each other on the same point on the y axis?

Best ResponseYou've already chosen the best response.0and at (log2,2) i think. thats all i know so far

Best ResponseYou've already chosen the best response.2thats correct, @emilyoo so now u have 2 points on that line,can u find the equation of that line?

Best ResponseYou've already chosen the best response.0then toy can find the equation of the line by using the two point formula of line i.e \[(yy1)=\frac{ y2y1 }{ x2x1 }\times(xx1)\] And the arrange the equation in the form x/a+b/b=1 and the value of a will be the x intercept of theline

Best ResponseYou've already chosen the best response.0i dont understand how you change the equation in the form x/a+b/b=1... what is b supposed to represent?

Best ResponseYou've already chosen the best response.0a and b are nothing but constants. And first solve the two point equation of the line. You will get a euqation in x, y and some constant value. Now take the constant to one side of the equaltiy and x and y to the other. Divide both the sides by the constant no on one side of the equation and you will get that form

Best ResponseYou've already chosen the best response.2since u have 2 points : (0,1) and (log 2,2) let the equation be y=mx+c. put (0,1)>c=1 put (log2,2) 2=m log 2 +1 m=1/(log 2) EQUATION :y=(1/log 2)x+1 x  intercept : 0=(1/log 2)x+1 x=log 2 is the xintercept. got this ??
