Q
Q: If f(x) = x^2, what is f(-3)?
Solution:
f(-3) = (-3)^2 = 9.
Steps: 6
Show Steps
Step 1: Identify the function f(x) which is given as f(x) = x^2.
Step 2: Substitute -3 into the function for x. This means we will calculate f(-3).
Step 3: Replace x in the function with -3. So, we have f(-3) = (-3)^2.
Step 4: Calculate (-3)^2. This means multiplying -3 by itself: -3 * -3.
Step 5: The result of -3 * -3 is 9.
Step 6: Therefore, f(-3) = 9.
