Q
Q: If f(x) = x^2 - 4x + 3, what is the value of f(2)?
Solution:
f(2) = 2^2 - 4*2 + 3 = 4 - 8 + 3 = -1.
Steps: 8
Show Steps
Step 1: Identify the function f(x) = x^2 - 4x + 3.
Step 2: Substitute x with 2 in the function to find f(2).
Step 3: Calculate 2^2, which is 4.
Step 4: Calculate -4 * 2, which is -8.
Step 5: Add the results from Step 3 and Step 4 to 3: 4 - 8 + 3.
Step 6: First, calculate 4 - 8, which equals -4.
Step 7: Now, add -4 and 3: -4 + 3 equals -1.
Step 8: Therefore, the value of f(2) is -1.
