Can someone please do these questions for me

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000

Consider the linear function that is represented by the equation y= 4x+5
