Answer 1

8x

Explanation:

Pls I hope this helps

Answer 2

8x

Explanation:

Using differentiation from first principles

f'(x) =
`lim_(h>0)`
`(f(x+h)-f(x))/(h)`

=
`lim_(h>0)`
`(4(x+h)^2-2-(4x^2-2))/(h)`

=
`lim_(h>0)`
`(4x^2+8hx+4h^2-4x^2+2)/(h)`

=
`lim_(h>0)`
`(8hx+4h^2)/(h)`

=
`lim_(h>0)`
`(4h(2x+h))/(h)` ← cancel the h on numerator/denominator

= 4(2x)

= 8x
