Question

Plot graph of a function $y={\log }_{2}x$ and state which of the following point does not lie on the graph of $y$.

• A. $(2,1)$
• B. $(4,2)$
• C. $(16,3)$
• D. $(32,5)$

Answer 1

Answer: (C)

$(16,3)$

$y={\log }_{2}x\Rightarrow x=2^y$

So any point on the curve is of form $(2^y,y)$

Clearly option $C$ do not satisfy the parametric point on the curve.

So option $C$ is correct.
