Answer:  

a)  Alawys positive:  t = 0 to a

b)   Decreasing at an increasing rate:  t = a to b

Step-by-step explanation:  The population is <u>increasing most rapidly</u> during the period the curve in rising.  The derivative of this line (i.e., the slope at any point t) will be positive until it t reaches a, the peak.  The slope at this point is zero, and it sill be negative after that point.  The values of t for which the slope is always positive are from 0 to a.  The population is decreasing at an increasing rate from a to b, where it slowly begins to slow until it reaches a steady population.

The graph of a quadratic function intercepts the x-axis in the two places and the y-axis in one place.
wolverine [178]
Correct Answer:
Option 3: <span>The quadratic function has two distinct real zeros.

The function is quadratic, therefore it can have only 2 zeros. The knowledge of x-intercepts is needed to determine the zeros, y-intercepts has nothing to do with the zeros of a function. The given function has 2 unique x-intercepts, so according to the fundamental theorem of algebra, this function has 2 distinct real roots as number of distinct real roots are equal to the number of x-intercepts. Therefore, option 3 is the correct answer. </span>

BlackZzzverrR [31]

Answer:

-14

Step-by-step explanation:

f(x) = 3x-5

g(x) = -x^2 +1

g(2) = - (2^2) +1

g(2) =-4+1 = -3

Then stick the -3 in f(x)

f(-3) = 3(-3)-5 = -9 -5 = -14

f(g(2) = -14
