Q
Q: If f(x) = x^3 - 3x + 2, what is f(1)?
Solution:
f(1) = 1^3 - 3(1) + 2 = 1 - 3 + 2 = 0.
Steps: 8
Show Steps
Step 1: Identify the function f(x) = x^3 - 3x + 2.
Step 2: Substitute x with 1 in the function: f(1) = 1^3 - 3(1) + 2.
Step 3: Calculate 1^3, which is 1.
Step 4: Calculate -3(1), which is -3.
Step 5: Now, combine the results: f(1) = 1 - 3 + 2.
Step 6: First, do 1 - 3, which equals -2.
Step 7: Then, add 2 to -2: -2 + 2 equals 0.
Step 8: Therefore, f(1) = 0.
