The graphs of three functions are shown.
i need !

a = 2

b = - 0.33333333 or - 1/3. I would try the decimal first.

Step-by-step explanation:

The black one is f(x) = x^2. You can check this out by putting 2 in for x. The graph will read y = 4. The graph also shows that if x = +/-3 then y = 9

The blue line indicates that a > 1. It is positive.

y = ax^2

Let x = 2. If x = 2 then y =8

8 = a*2^2

8 = a * 4         Divide both sides by 4

8/4 = a*4/4

a = 2

g(x) = 2*x^2

The black inverted graph shows that x^2 is upside down. Therefore b<0. Furthermore, the graph is spread out a bit more than f(x) = x^2 b is a fractional amount.

When x = 3, y = 3

y = - b x^2

3 = - b 3^2

3 = - b * 9

3/9 = -b* 9

b = - 3/9 = - 1/3

This is a bit nasty. It's hard to know what the computer will accept. the answer is -1/3 or -0.3333333    

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
