Q
Q: If f(x) = 2x + 3, what is f(5)?
Solution:
f(5) = 2(5) + 3 = 10 + 3 = 13.
Steps: 5
Show Steps
Step 1: Identify the function f(x) which is given as f(x) = 2x + 3.
Step 2: Substitute the value of x with 5 in the function. This means we replace x with 5 in the equation.
Step 3: Calculate 2 times 5. This gives us 2(5) = 10.
Step 4: Add 3 to the result from Step 3. So, we calculate 10 + 3.
Step 5: The final result is 13, which means f(5) = 13.
