$\int 8\, dx=8x+C\\\\
0=8\cdot1+C\\
C=-8\\
f'(x)=8x-8\\\\
\int 8x-8\, dx=4x^2-8x+C\\\\
3=4\cdot1^2-8\cdot1+C\\
3=4-8+C\\
C=7\\\\
\boxed{f(x)=4x^2-8x+7}

A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less than 3

pav-90 [236]

1/3, because the probability in the cube is 1/6, and there are 2 numbers less than 3. So, 2/6 and simplify 2/6 to 1/3.
