Manipal MET2011MathematicsContinuity and Differentiability
The value of f(0) , so that the function f(x)= 2-(256-7 x)^ 1 / 8 (5 x+3 x)^ 1 / 5 -2 , x 0 is continuous everywhere is given by
Options
- A-1
- B1
- C2^6
- DNone of these
Correct answer
D. None of these
Step-by-step solution
For f(x) to be continuous everywhere, we must have aligned f(0) & = _ x 0 f(x) & = _ x 0 2-(256-7 x)^ 1 / 8 (5 x+32)^ 1 / 5 -2 & = _ x 0 7 8 (256-7 x)^ -7 / 8 (5 x+32)^ -4 / 5 & = 7 8 2⁻⁷ 2⁻⁴ = 7 64 aligned
