4 question to be answered only use derivation rules Please I need this in 20 minutes

I use Irnear approximation Be the tangent line, to approximate 3764. 4 as follows, Let JOXJ = 3/7 The equation of tangent line to togatx = Gucan be written in the from y = mxtb Where m, rounded 6 decimal Places , si and lontown where b, rounded 6 decimal places is using this , we find our approximation for 31 64- 4 rounded to 6 decimal places is Find the critical value (ssot J( XJ = 24x-x to two decimal placesas needed, separate multiple answers with compa J(x) has Cirtical values at X = $ use calculus to identify the intervals of increase and decrease of Joysix- f(xle- 17 ( x - 14 ) 2 express your answers exactly in I notations The fuction is increasing on The fuction Is decreasing on 4 lim 4 X--00 exex + 2
