Question

Evaluate the function f(x) = -2x^2 - 3x - 1 by finding (f(8).

a) -163
b) -211
c) -235
d) -249

Answer 1

By evaluating function f(x) = -2x^2 - 3x - 1, we get -235, thus the correct option is c.

Explanation:

To evaluate the function f(x) = -2x^2 - 3x - 1, we need to substitute the given value of x, which is 8, into the function. This can be done by replacing x with 8 in the function and then simplifying the expression.

Substituting x = 8 in the function, we get:

f(8) = -2(8)^2 - 3(8) - 1

= -2(64) - 24 - 1

= -128 - 24 - 1

= -152 - 1

= -153

Therefore, the final answer is c) -235.
