Hi there!
Begin by differentiating f(x) using the power rule:
dy/dx = nxⁿ⁻¹
Therefore:
f(x) = 3x² - 5x + 10
f'(x) = 6x - 5
Set this equation equal to 0 to find the x-intercept:
0 = 6x - 5
5 = 6x
x = 5/6, which is where the graph goes from NEGATIVE to POSITIVE, so there is a MINIMUM at this value.
For this case we have to take into account the following conversions:
Let's first transform the expression to miles per seconds squared:
Then, we transform the result to miles per minute squared.
We have then:
Answer:
the rate in miles/min^2 is:
