WebFinding Intercepts From an Equation. To find the intercepts: When you want the x intercepts (x,0): Set y=0 then solve for x. When you want the y intercepts (0,y): Set x=0 then solve for y. WebMar 18, 2024 · f ( x) = 3 − 4 log 10 ( 2 x) and set. f ( x) = 0. which gives. 3 = 4 log 10 ( 2 x) 3 4 = log 10 ( 2 x) Now log a b = c implies a c = b or like you have done log 10 ( 2 x) = log 10 10 3 / 4 which gives. 10 3 / 4 = 2 x. x = 10 3 / 4 2.
