Question

someone help me with derivatives

Answer 1

for the following function , find the derivative and evaluate at x=2 , -4, 0 and pi

Answer 2

where is the function ??

Answer 3

Y=2x

Answer 4

f(x)=2x
f'(x)=2

Answer 5

the derivative is linear
so you cannot substitute values in

Answer 6

unless it is asking you to evaluate the original function

Answer 7

ok thanks so then the answer is y'=2

Answer 8

how do i evaluate it at x=2, -4, 0, pi

Answer 9

that just means substituting the x-values into the function

but f'(x)=2 does NOT have any x-values included since its linear (therefore, a straight line on the graph)

Answer 10

so that does mean that every number for example y'(-4) = 2

Answer 11

basically, for the derivative

for every x-value, the y-value stays as 2

Answer 12

so if you were to graph it it would just be

Answer 13

and the original f(x) [function] looks like
