Answer 1

\(e^2cos(x)\)

Answer 2

\(f(x)=x^2+4x-12\)
\(y=x^2-2x+6x-12\)
\(y=x(x-2)+6(x-2)\)
\(y=(x-2)(x+6)\) thus: \(x_1=2\) and \(x_2=-6\)

Answer 3

\(\frac{2}{cos(x)}\)

Answer 4

\[\sqrt\frac{1}{x^2+2}-\frac{2x}{6y}\]
\(\frac{33}{26}\)

Answer 5

\[sin(\theta)\times cos(\theta)\]

Answer 6

\[360=2\pi\]

Answer 7

\[\sqrt{16}=\pm4\]

Answer 8

\[\huge{size}\] \huge{size}

Answer 9

\[\huge{\sqrt[n]{x}}\]

Answer 10

\[\large{ f(x)=\sqrt[3]{x} \\
y=\sqrt[3]{x} \\
f^{-1}(x)=x=\sqrt[3]{y} \\
f^{-1}(x)=x^3=y \\
f^{-1}(x)=x^3
}\]
