The value of c, the constant of the function y = ax² + bx + c, is -3
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that:
y = ax² + bx + c
At point (4, 21)
21 = a(4²) + 4b + c (1)
At point (5, 32)
32 = a(5²) + 5b + c (2)
At point (6, 45)
45 = a(6²) + 6b + c (3)
Hence:
a = 1, b = 2 and c = -3
The value of c, the constant of the function y = ax² + bx + c, is -3
