2(x2 + 6) – 3 vy when x = 3 and y = 64.

73

Step-by-step explanation:

you would do distributive property we know x= 3 so on the inside would be 32 now since we are doing distributive property you multiply 32x2 and 6x2

then you add them together and after you subtract 3 from 76 which = 73

a) you can graph the equation to see the value of d required to make f(d) be 13.29. it is about 11. then the domain of the function might reasonably be specified as the interval [0, 11]

b) the y-intercept is f(0) = 7, the radius of the algae when the biologist began her study.

c) the average rate of change of a function over the interval [a, b] is (f(b)-f(a))/(b-a). for this function, it is about 0.636 mm/day. this represents the average change in radius (mm) of the algae each day of the last week of the study.
