The tangent line to the graph of {eq}y = g(x) {/eq} at the point {eq}(6, 8) {/eq} passes through the point {eq}(1, 3) {/eq}. Find {eq}g(6) {/eq} and {eq}g'(6) {/eq}. Tangent Lines: A tangent line can be expresse...
Recall that the derivative of a function at a point is equal to the value of the slope of the line tangent to the curve at that point. So we need to find the derivative here. When we differentiate an implicit function, we must be careful to follow the chain...
