Let, f(x)=sinx-cosx ;[-π,π). find (a) the intervals on which f is increasing. (b) the intervals on which f is decreasing. (c) the intervals on which f is concave up (d) the open intervals on which f is concave down and (e) the x-co ordinates of all inflection points​

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
