Answer

indeterminate, 2

Work Step by Step

See the table: "Some Determinate and lndeterminate Forms" and, after plugging in the value for x, recognize the indeterminate form $\displaystyle \frac{0}{0}$. From "Strategy for Evaluating Limits Algebraically" step2, ** $f(\mathrm{a})$ is not defined and has the indeterminate fom 0/0. Try to simplify the expression for $f$ to cancel one of the terms that gives $0$. Divide both the numerator and denominator with $x^{2}.$ $\displaystyle \lim_{\mathrm{x}\rightarrow 0}\frac{2x^{2}\div x^{2}}{x^{2}\div x^{2}}=\lim_{\mathrm{x}\rightarrow 0}2=2$
