To solve the problem shown in the figure above you must keep on mind the following information:
1. The figure shows a parabola whose vertex is (0,0).
2. The x² indicates that the red parabola shown in the figure is vertical
3. and the sign - indicates that the red parabola opens down.
Therefore, you can conclude that the red parabola has the equation f(x)=-x²
So, the answer is B.

Lets get started :)
2 + 2 + x - 7 = 21
11 + x = 21
We have to subtract 11 on both sides to isolate x
11 ( - 11 ) + x = 21 ( - 11 )
11 and 11 cancels out
x = 10

Answer: Statement B in the lower left corner</h3>
When you raise an exponential expression to another exponent, you multiply the exponents. We have 8*5 = 40 as the final exponent. The rule is (x^y)^z = x^(y*z). The base stays the same.
Statement A is not true because we should be adding the exponents. The rule is x^y*x^z = x^(y+z). Note how the bases are all the same. We'll use this rule for statement C to show that it is also false.
A similar rule is (x^y)/(x^z) = x^(y-z). We subtract the exponents this time. This rule is used to show that statement D is false.
