Question 746939: hi. this is really important and URGENT. i have got a test tomorow and this type of question would definitely be there. please help me out.
the question is: the slope of a taangent is 3. the point on the tangent is (3,5). the tangent intersects the equation: y=ax^4+bx^2+cx+d. find the a,b and c and d values. this question is part of grade 12 calculus. I REALLY APPRECIATE ANY HELP GIVEN. THANKYOU.

the question is: the slope of a taangent is 3. the point on the tangent is (3,5). the tangent intersects the equation: y=ax^4+bx^2+cx+d. find the a,b and c and d values. this question is part of grade 12 calculus.
---------------------
y=ax^4+bx^2+cx+d
5 = 81a + 9b + 3c + d (from the point (3,5))
---
y' = 4ax^3 + 2bx + c
3 = 108a + 6b + c

2 equations with 4 variables --> not enough info.
