Our parabola open downward and therefore a is negative.
Explanation:
As value of a changes from positive to negative or from negative to positive, the direction of opening changes. For negative values of a we got negative parabolas that open downward. As the original formula y = x^2 we see that x^2 will always be positive because when you square a number it always gives positive value. Therefore the direction for which it will open, depends on value of a.
Answer:
Step-by-step explanation:
find f(x) first because it is in the parenthesis
2^6=2*2*2*2*2*2=64
Since the exponent is negative, we put the 64 over 1
1/64
