Solving Exponential and Logarithmic Equations

log2(5 10b (4) (1) (2) f(x) = log2(2x — 2) g(x) = 5 — log2(x — 1) Illustrate graphically. Solution There is one point of intersection at x = 5. Find the y-coordinate of the point by determining f(5) or g(5). f(5) = — 2) = log2(8) Therefore, the two functions intersect at (5, 3) g(5) Examples Example 7 ................
