Evaluate the estimate slope of f(x)= x 2 +1 (i) x=1 (ii) x= 2 pls guys help me i need the answer fast please

i.2

ii.4

Step-by-step explanation:

to estimate a slope simply means to differentiate,

from the equation:f(x)=x^2+1

dx/dy=2x+0=2x

where x=1

it becomes:2(1)=2

where x=2

it becomes:2(2)=4

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

hm let me think hm think think hm think yes
