Question
Find an equation of the straight line tangent to the given curve at the point indicated.$$y=2 x^{2}-5 \text { at }(2,3)$$
Step 1
The derivative of a function at a certain point gives us the slope of the tangent line at that point. The derivative of the function $y=2x^{2}-5$ is given by: $$\frac{dy}{dx}=4x$$ Show more…
