Question

If ƒ (x) = 3x²+1 — 1, what is the value of f(−1), to the nearest ten-thousandth (if necessary)?

Answer 1

To find the value of f(-1), we need to substitute -1 for x in the given function:

f(x) = 3x² + 1 - 1

f(-1) = 3(-1)² + 1 - 1

f(-1) = 3(1) + 0

f(-1) = 3

Therefore, f(-1) is equal to 3.
