Question

determine whether the curve has a tangent at the indicated point. If it does, give its slope. If not, explain why not.

Answer 1

Answer:

Explanation:

By solving the two equations you will get a point

(

x

,

y

)

which lies on both the curve and the straight line.

if you got more than one point then this line will be intersecting and not a tangent to the curve.

then by finding the first derivative of the curve and substituting with the value of the point

(

x

,

y

)

if it's value is equal to the slope of the straight line then this line is its tangent.
