The <em>correct answer</em> is:
f(x) = -10x², f(x) = 2x², and f(x) = 0.5x²
Explanation:
For a quadratic in standard form, f(x) = ax²+bx+c, the value of a describes the width and direction of the parabola. If a is positive, the parabola is open upward. If a is negative, the parabola is open downward.
If a < 1, a fraction or decimal, the graph is wider than the parent function f(x)=x². If a > 1, the graph is narrower than the parent function f(x)=x². The larger the value of a is (a > 1), the narrower the graph is. This makes the function with the decimal value of a the widest; the remaining graphs are in order of the value of a, least to greatest.
The next 3 numbers are 184, 375, and 758. Subtract the numbers (8-3, 19-8, 43-19 etc) you get a trend of 5, 11, 23, 47 and 95, if you subtract those (11-5, 23-11, 47-23) you get a trend of 6, 12, 24, which is just multiplied by 2 (6 x2 is 12, 12x 2 is 24). You can complete that by multiplying by two. You’ll notice that compared with that on both sides you’ve got 6, 12, 24, 48, and on another side you’ve got 5, 11, 23, 47 (one side is smaller by 1). You can add to get the next number in the sequence from 5, 11, 23, 47, etc. (3+5=8, 8+11=19........89+95=184, 184+191= 375, 375+ 383= 758. Hope that helped
