# Function Graphs

Graphs are visual representations of functions. If you know how to read graphs, you can say a lot about a function just by looking at its graph. Learn this fine art of mathematical divining.

(i) Translate **B** by \(-7\) and \(-5\) in the positive directions of the \(x\)-axis and \(y\)-axis, respectively, and stretch by a factor of \(2\) with respect to the \(y\)-axis.

(ii) Translate **B** by \(-7\) and \(-5\) in the positive directions of the \(x\)-axis and \(y\)-axis, respectively, and stretch by a factor of \(2\) with respect to the \(x\)-axis.

(iii) Translate **B** by \(7\) and \(5\) in the positive directions of the \(x\)-axis and \(y\)-axis, respectively, and stretch by a factor of \(\frac{1}{2}\) with respect to the \(y\)-axis.

(iv) Translate **B** by \(-7\) and \(-5\) in the positive directions of the \(x\)-axis and \(y\)-axis, respectively, and stretch by a factor of \(\frac{1}{2}\) with respect to the \(x\)-axis.

\(\quad \text{(1)}\) Translate to the left by 1 and up by \( \ln 4 \), then scale vertically by 2.

\(\quad \text{(2)}\) Translate to the left by \(\frac{1}{2}\) and up by \( \ln 2 \), then scale vertically by 2.

\(\quad \text{(3)}\) Translate to the left by 1 and up by \( \ln 2 \), then scale vertically by 2.

\(\quad \text{(4)}\) Translate to the left by \( \frac{1}{2} \) and up by \( \ln 4 \), then scale vertically by 2.

**Note:** The above graph is not drawn to scale.

(i) Stretch the given graph by a factor of \(5\) with respect to the \(x\)-axis and translate by \(4\) in the positive direction of the \(x\)-axis.

(ii) Stretch the given graph by a factor of \(5\) with respect to the \(y\)-axis and translate by \(-4\) in the positive direction of the \(y\)-axis.

(iii) Stretch the given graph by a factor of \(\frac{1}{5}\) with respect to the \(x\)-axis and translate by \(4\) in the positive direction of the \(y\)-axis.

(iv) Stretch the given graph by a factor of \(\frac{1}{5}\) with respect to the \(x\)-axis and translate by \(-4\) in the positive direction of the \(y\)-axis.
