Explanation / Answer

1)Velocity is the integral of acceleration is true

2. f '(x) = 3x2 -3x and f(0) = 12. Find f(2). Give your answer correct to two decimal places.

f(x)= integral f '(x) dx

f(x)= integral 3x2 -3x dx

f(x)= 3x3/3-3x2/2 +c

f(x)= x3-3x2/2 +c

f(0)= 03-3*02/2 +c =12

==>c=12

f(x)= x3-3x2/2 +12

f(2)= 23-3*22/2 +12

f(2)=8-6+12

f(2)= 14

3. f'(x) = 6x+10 and f(1) = 10. Find f(4)

f(x)= integral f '(x) dx

f(x)= integral 6x+10 dx

f(x)= 6x2/2 +10x +c

f(x)= 3x2 +10x +c

f(1)= 3*12 +10*1 +c=10

c=-3

f(x)= 3x2 +10x -3

f(4)= 3*42 +10*4 -3

f(4)= 85
