Evaluate f(x)= 4x^2 - 2 for f(1/2)
To evaluate the function f(x) = 4x^2 - 2 at f(1/2), we substitute the value 1/2 in place of x in the function expression and compute the result.
f(1/2) = 4(1/2)^2 - 2
To simplify further, we square 1/2:
f(1/2) = 4(1/4) - 2
Now, we multiply 4 by 1/4:
f(1/2) = 1 - 2
Finally, subtract 2 from 1:
f(1/2) = -1
Therefore, the value of f(1/2) is -1.
