Suppose f and g both are linear function with f(x) = – 2x + 1 and f(g(x)) = 6x – 7 and slope of y = g(x) be m then 3 – m is equal to
Text Solution
Verified by ExpertsThe correct answer is:
6
Ans. 6
Sol. Let g(x) = ax + b
⇒ f(ax + b) = 6x – 7
⇒ –2ax – 2b + 1 = 6x – 7
⇒ b = 3, a = – 3
∴ m = – 3
∴ 3 – m = 3 – (– 3) = 6
