a. Find an equation for the secant line through the points where \( \mathrm{x} \) has the given values. b. Find an equation for the line tangent to the curve when \( x \) has the first value. \[ y=2 \sqrt{x} ; \quad x=4, \quad x=9 \] a. The equation for the secant line is \( y= \) b. The equation for the tangent line is \( y= \)
Expert Answer
Let y=2 ?x;x=4, x=9 The two points on the secant line are: x=4 and y=2 ?4=2(2)=4 ; coordinate: (x1,y1) =( 4,4 ) x=9 and y=2 ?9=2(3)=6 ; coordinate: (x
