a ^ 2 / a ^ 9
For this case what you should do is use the power properties to write the expression in different ways.
Three different ways to write the expression are:
Way 1:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7) = 1 / a ^ 7
1 / a ^ 7
Way 2:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7)
a ^ (- 7)
Way 3:
a ^ 2 / a ^ 9 = a ^ 2 * a ^ (- 9)
a ^ 2 * a ^ (- 9)
Answer:
all the equivalent to a ^ 2 / a ^ 9 are:
1 / a ^ 7
a ^ (- 7)
a ^ 2 * a ^ (- 9)
F(x) = -x^2 + 3x + 8
f'(x) = -2x + 3
when f(x) is increasing f'(x) > 0
-2x + 3 > 0
-2x > -3
x < 3/2 or 1.5
So the required interval is (-infinity,1.5).The first choice.
B , because the all go by half until it goes up more
The answer is : So What you basically need to do is circle and fill over 0 and 4. The answer would be C. A and B are wrong you need to look out for the signs basically. Hope this helps
