- Question 1 of 10
##### 1. Question

State whether $y=x-1$ is a function or not.

CorrectIncorrect##### Hint

The relation is a function if each vertical line cuts the graph no more than once.

- Question 2 of 10
##### 2. Question

Given \(f\left( x \right) = ax + b\), \(f\left( 1 \right) = 7\) and \(f\left( 2 \right) = 10\), find \(a \) and \(b\).

\(a = \)

\(b = \)

CorrectIncorrect - Question 3 of 10
##### 3. Question

State the domain and range of \(y = \dfrac{x}{{x + 1}}\).

CorrectIncorrect - Question 4 of 10
##### 4. Question

Find the equation of the graph in red, where the graph of $y=2^x$ is given in blue.

CorrectIncorrect##### Hint

$y=a^x$ is shifted to the right by $b$ units, $y=a^{x-b}$.

$y=a^x$ is shifted to the left by $b$ units, $y=a^{x+b}$.

$y=a^x$ is shifted up by $c$ units, $y=a^x + c$.

$y=a^x$ is shifted down by $c$ units, $y=a^x – c$. - Question 5 of 10
