Question

the curve with the equation y=ax^2 + bx + c passes through the point (-1,4). at the point (2,7), the gradient of the curve is 7. find the value of a, b, c​

Answer 1

Answer:

Step-by-step explanation:

These conditions must be satisfied:

6 = a*2^2 + b*2 + c = 4a + 2b + c

16 = 9a + 3b + c

dy/dx @ P = 2a*2 + b = 4a + b = 7
