I don't even know where to begin on this question! It's grade 12 calculus. We just finished learning the chain rule.
25. The graph of y=(ax+b)^c, where a,b,c are real constants, has a tangent line at (3,27) defined by y=18x-135. The graph also has a point of inflection, (-1.5, 0). Determine a, b, c.
At the very least, help me to get started by solving for one of these variables!
Please and thank you.
yes, I got that far. And then I had subbed 3 into x. But at that point, I still have 3 variables and one equation... At grade 12 calculus, at the very BEST of times, the most we have ever been taught/can do is solve for 2 variables by subbing one equation into another. I have no diea how to deal with all 3 variables here. :S
