Question 1 of 8

Calculator allowed

The function, domain restriction and interval are shown below

f(x)=\log_e\left(x\right)

The domain is \(\left(0,\,\infty\right)\), where the function is one-to-one

The input interval is

p=1,\quad q=e^{\frac{7}{2}}

Calculate the area under the curve from the displayed data

Choose the domain of \(f\) and the matching domain and range of \(f^{-1}\)

D_f=\left(-\infty,0\right),\quad R_f=\mathbb{R};\quad D_f^{-1}=\mathbb{R},\quad R_f^{-1}=\left(-\infty,0\right)

D_f=\left[0,\,\infty\right),\quad R_f=\mathbb{R};\quad D_f^{-1}=\mathbb{R},\quad R_f^{-1}=\left[0,\,\infty\right)

D_f=\mathbb{R},\quad R_f=\mathbb{R};\quad D_f^{-1}=\mathbb{R},\quad R_f^{-1}=\mathbb{R}

D_f=\left(0,\,\infty\right),\quad R_f=\mathbb{R};\quad D_f^{-1}=\mathbb{R},\quad R_f^{-1}=\left(0,\,\infty\right)

Select the inverse rule for the stated function

f^{-1}(y)=e^{y} + 1

f^{-1}(y)=\log_e\left(y\right)

f^{-1}(y)=\frac{e^{y}}{2}

f^{-1}(y)=e^{y}

f^{-1}(y)=e^{2y} + 1

Complete the displayed inverse rule by entering the three missing values

f^{-1}(y)=\frac{e^{y/\square}+\square}{\square}

denominator in the exponent constant added to the exponential denominator outside the numerator
