Answer:
Step-by-step explanation:
To find f(3) for the function f(x) = 2x + 4, it means you substitute (x) with (3) in the function. So, you replace every occurrence of (x) with (3) and calculate the result:
[f(3) = 2 \times 3 + 4]
Solving this expression:
[f(3) = 6 + 4 = 10]
Therefore, (f(3) = 10). It does not involve multiplying everything by (3), letting (x) equal (3) (which is what you did in this case), multiplying \(f\) by \(3\), or raising everything to the (3)rd power. The notation (f(3))simply represents the value of the function when the input (x) is (3).
