Find an equation of a line that is tangent to the curve and is parallel to the line definition of a derivative
-
The equation of line of tangent is :y=1/2x+7/2 and y=1/2x-1/2.According to the statementwe have to find the equation of the line with the help of the given curve.So, For this purpose, we know that theThe given information is:The equations of the tangent lines to the curve is y= (x-1)/(x+1) and the that are parallel to the line x-2y = 2.So,A line parallel to x-2y = 2 must have the same slope. The slope of this line is 1/2.So we want the slope of the tangent line to be 1/2.Now we find the derivative of the y= (x-1)/(x+1)So,By quotient rule the derivative becomey’= (x(x+1)-(x-1)*1)/(x+1)^2y’ = 2/(x+1)^2So,Now find the value of the x with the help of y’.So,2/(x+1)^2 = 1/2And solve it thenx = 1 and -3.So, x = 1 and x = -3.Now, the value of y become:At x = 1, y = 0 andx = -3, y = 2.thenThe equation of lines with point (1,0) and slope 1/2.And The equation of lines with point (-3,2) and slope 1/2.So, The equation of line of tangent is :y=1/2x+7/2 and y=1/2x-1/2.Learn more about equation of line herehttps://brainly.com/question/13763238Disclaimer: This question was incomplete.
