Final answer:
To find the unknown coefficients 'a' and 'c' in the given equation y = c - ax² - 2x, we substitute the given point (-1, 3) into the equation and solve for 'a' and 'c'.
Step-by-step explanation:
To find the unknown coefficients, we need to substitute the given point (-1, 3) into the equation and solve for 'a' and 'c'.
Substituting the values:
3 = c - a(-1)^2 - 2(-1)
3 = c - a + 2
Next, we simplify the equation:
3 = c - a + 2
1 = c - a
Finally, we can't determine the values of 'a' and 'c' without additional information. The equation is dependent on another equation or given values.
