The graph C shows a function
The other options all have an x-value that has two y-values.
Functions need unique mappings from every point in the domain.
The correct statements about the equation are b, c, and e.

<h3>Polynomial;</h3>
The highest power of the polynomial is called the degree of the polynomial.
We have to determine
Which equation accurately represents this statement?
Statement; Negative 3 less than 4.9 times a number, x, is the same as 12.8.
Then,
The equation accurately represents this statement is;

Hence, the correct statements about the equation are b, c, and e.

Answer:
3/7
Step-by-step explanation:
HCF of 21 and 49 = 7
21 / 49 = (21/7) / (49/7) = 21/7 *7/49 = 3 * 1/7 = 3/7
