The terms of a polynomial are the individual components that are summed together, which are typically formed by a coefficient multiplied by a variable raised to a power.
For the polynomial \( 6x^2 + \frac{4}{7}y^2 - 4x - 45 \), we identify the following terms:
- \( 6x^2 \)
- \( \frac{4}{7}y^2 \)
- \( -4x \)
- \( -45 \)
Therefore, the correct answer is:
E. \( 6x^2, \frac{4}{7}y^2, -4x, \) and \( -45 \).
