Question

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

Answer 1

i.2

ii.4

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
