The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7

<h3>The dimension of the matrix?</h3>

From the figure in the question, we have the following highlights:

The matrix has 3 rows
The matrix has 3 columns

The dimensions of a matrix are represented by: Row by column

Hence, the dimensions of the matrix are 3 by 3

<h3>The indicated element</h3>

This is given as:

a₂₃

This means that the element is located at the second row and the third column.

The element at this position is -7

Hence, the indicated element is -7

The graph of g is one-fifth as steep as the graph of f.

The function g basically takes the inputs for f and multiplies them by one-fifth, which means the outputs are one-fifth times those of f. Multiplying by one-fifth makes something smaller (it's the same as dividing by five). It helps to visualize this relationship, so I've attache the graphs below.
