Isabella was asked to determine whether f(x)=3x4+6x−2 is even, odd, or neither. Here is her work. Step 1: Find the expression for f(−x). f(−x)=3(−x)4+6x−2=3x4+6x−2 Step 2: Check if f(−x) is equal to f(x) or −f(x). f(−x)=f(x), and f(−x)≠−f(x). Step 3: Conclude that f(−x) is equivalent to f(x), so f must be even. Is Isabella's work correct? If not, what is the first step where Isabella made a mistake?
Isabella's work is correct.
Isabella's work is not correct. She made her first mistake in step 3.
