Question

Use the Fundamental Theorem to determine the value of b if the area under the graph of f(x)=8x between x=1 and x=b is equal to96. Assume b>1

b=?

Answer 1

and the fundamental thrm states?

Answer 2

\[\int_{a}^{b} F'~dx=F(b)-F(a)\]

Answer 3

\[\int\limits_{1}^{b}8xdx = 96\]

Answer 4

I got the answer it is 5

Answer 5

ida used a ~ to space the dx ... but thats just me being persnickety

Answer 6

show your work!!

Answer 7

what do you get for the antiderivative ?... just dont get enough chances to use that obsolete term ..
