In f(x) = a(x - p)(x - 9), what does "a" tell us?

1 answer:

4 0

Answer:

Step-by-step explanation:

f(x) = a(x-p)(x-9) is the equation of a vertical parabola.

If a>0, the parabola opens upwards.

If a<0, the parabola opens downwards.

Also, the focal length of the parabola is 1/|4a|.

$\sqrt{5}\cdot\sqrt[3]{5} =\sqrt[6]{5^3} \cdot\sqrt[6]{5^2} =\sqrt[6]{5^5} =5^{(5/6)}$

Step-by-step explanation:

The rules of exponents apply, even when they are fractional exponents:

$a^b\cdot a^c=a^{b+c}\\\\\sqrt[b]{x^a}=x^{(a/b)}$
