The derivative of a function f at a point x is denoted as `y' = f'(x)`
There are basic properties and formula we can apply to simplify a function such as the Product Rule provides the formula:
`d/dx(u*v) = u' *v + u * v'`
For the problem:`g(t) = t^2* 2^t` we let :
`u = t^2`
`v = 2^t`
Now we want to find the derivative of each function.
Recall the power rule for derivatives:`d/dx(u^n)=n*u^(n-1) du/dx `
So, for `u = t^2` ,
`u' = 2t`
Recall that for differentiating exponential functions:
`d/dx(a^u) =a^u* ln(a)*du/dx` where `a!=1` .
With the function` v = 2^t` , we get `v' = 2^t*ln(2) *1 = 2^tln(2)`
We now have:
`u = t^2`
`u' = 2t`
`v=2^t`
`v' =2^tln(2)`
Then following the Product Rule:`d/(dx)(u*v) = u' *v + u * v'`, we get:
`g'(t) = 2t*2^t + t^2* 2^tln(2)`
g'(t) = `t2^(t+1) + t^2 2^tln(2` ) `
