Final answer:
To evaluate f - g + (-2), substitute the values of f and g into the expression and simplify to find the result.
Step-by-step explanation:
To evaluate the expression f - g + (-2), we substitute the given values of f and g into the expression:
f - g + (-2) = -3.005 - 4.7 + (-2)
Next, we simplify the expression by performing the subtraction and addition:
-3.005 - 4.7 + (-2) = -7.705 + (-2) = -9.705
Therefore, the value of f - g + (-2) is -9.705.
