F(x)=x^2e^x a a) determine the intervals on which f is concave up and concave down. f is concave up on: f is concave down on: b) based on your answer to part (a), determine the inflection points of f. each point should be entered as an ordered pair (that is, in the form (x, (separate multiple answers by commas.) c) find the critical numbers of f and use the second derivative test, when possible, to determine the relative extrema. list only the x-coordinates. relative maxima at: (separate multiple answers by commas.) relative minima at: (separate multiple answers by commas.)

susie has 7 apples

2.14x - 12.18 = -5.76

add 12.18 to each side

2.14x -12.18 +12.18 = -5.76 +12.18

2.14 x =6.42

divide by 2.14

2.14x/2.14 = 6.42/2.14

x=3

answer : the point moved thirteen places to the right

on the number line, a point is moved from -8 to 5

on a number line, negative numbers on the left side of 0   and positive numbers on the right side of 0.

to move from -8 to 5 , we move to the left

start from -8 , move to -7 then -6 then -5 then -4 then -3 then -2 then -1 then 0 then 1 then 2 then 3 then 4 and finally 5

so we moved 13 placed to the right.

the point moved thirteen places to the right
