Answer:
The turning point of the graph is at (3,-16)
Step-by-step explanation:
The general equation of curve is given as:
y = x² + ax + b
The two point for which the equation satisfies is (0,-7) and (7,0).
Substitute (0,-7) in the general equation:
y = x² + ax + b
-7 = 0² + a(0) + b
b = -7
Substitute (7,0) in the general equation:
y = x² + ax + b
0 = 7² + 7a + b
Where b = -7
0 = 49 + 7a - 7
0 = 42 + 7a
a = -6
The equation of the curve is:
a = -6 and b = -7
y = x² + ax + b
y = x² - 6x - 7
Graph of the equation is attached below.
We can see that the the turning point of the graph is at (3,-16)
The value of the expression a - b + c + d will be 7.
<h3>What is the matrix?</h3>A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
The system of equations are given below.
5x + 7y = 7
3x - 2y = 9
Then the equations can be written in the form of matrix. Then we have
Then the value of a, b, c, and d will be
a = 5, b = 3, c = 7, and d = -2
Then the value of the expression will be
a - b + c + d = 5 - 3 + 7 - 2
a - b + c + d = 12 - 5
a - b + c + d = 7
