Using the quadratic formula to solve 11x2 – 4x = 1, what are the values of x?

Option a is correct

Step-by-step explanation:

11x² - 4x = 1

Rewriting the equation:

11x² - 4x - 1 = 0

from above equation, a = 11, b = -4, c = -1

As we are asked to solve it with quadratic equation:

put values of a, b and c

taking 2 common above and cutting it with denominator

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
