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.

Isabella's work is not correct. She made her first mistake in step 2.

Isabella's work is not correct. She made her first mistake in step 1.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
