im trying to find the x intercept of the unknown line, not f(x)=10^x

@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...

So first find the equation of the line

@emilyoo Does the line and the curve intersect each other on the same point on the y axis?

and at (log2,2) i think. thats all i know so far

thats correct, @emilyoo so now u have 2 points on that line,can u find the equation of that line?

i got y1=log2(x)

punnus Group TitleBest ResponseYou've already chosen the best response.0
then 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

i dont understand how you change the equation in the form x/a+b/b=1... what is b supposed to represent?

punnus Group TitleBest ResponseYou've already chosen the best response.0
a 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

hartnn Group TitleBest ResponseYou've already chosen the best response.2
since 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 ??

sorry divide the eqn on both the sides
