Please use the actual limit definition for part B. Need this answer quickly to turn in soon

flx)=\/x+2 A.) Write an Expression for the slope of the secant line that passes through the point (x,f(x)) and (7,117)]B.)Use the limit defintion to find the slope of the line tangent to the graph of f{x) at x=7C.) Write the equation of the line tangent to the graph off at x=7 in point-slope form Show transcribed image text
