What number is \( 150 \% \) of \( 30 ? \)

Find the domain and range of the following relation. Also determine whether the relation is a function. \[ \{(4,2),(4,3),(4,5),(4,6)\} \]

a. Find the derivative function \( f^{\prime} \) for the function \( f \). b. Find an equation of the line tangent to the graph of \( f \) at \( (a, f(a)) \) for the given value of \( f(x)=2 x^{2}-x-3, a=2 \) a. \( f^{\prime}(x)=\square \)

9) \( 100 \mathrm{~m}^{2} \mathrm{n}^{4}-169 \mathrm{y}^{6}= \) omio cuadrado perfecto: \( \mathrm{m}^{2}+2 \mathrm{~m}+1= \) \( 4 \mathrm{x}^{2}+25 \mathrm{y}^{2}-20 \mathrm{xy}= \)

Solve the inequality and write the solution in interval notation. Leave answers in exact, simplified form. \[ 2 \mathrm{x}^{2}+4 \leq 8 \mathrm{x} \] Preview Get help: Written Example
