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