Final answer:
The value of f(-4) cannot be determined without knowing the specific function. Once the function is provided, substitute -4 into the formula of f(t), and calculate accordingly. For quadratic functions, use the quadratic formula to solve for t if necessary.
Step-by-step explanation:
To find the value of f(-4), we need the specific function formula for f which isn't provided. The value of f(-4) cannot be determined without knowing the specific function. Once the function is provided, substitute -4 into the formula of f(t), and calculate accordingly. For quadratic functions, use the quadratic formula to solve for t if necessary.
However, I can guide you on how to substitute the value into the function once you have it. If the function is given by a quadratic equation of the form at² + bt + c = 0, where a, b, and c are constants, you would substitute t with -4 and solve for f(-4).
For example, if the original quadratic function were f(t) = at² + bt + c, substituting -4 in for t would look like f(-4) = a(-4)² + b(-4) + c. You would then calculate the value by squaring -4, multiplying by a, and then adding the product of b and -4, and finally adding c.
Remember to use the quadratic formula if you need to solve for t when the function is equal to zero, which is t = (-b ± √(b² - 4ac)) / (2a).
