Answer:
Step-by-step explanation:
In each case, the axis of symmetry is the vertical line through the vertex.
<u>For f(x)</u>
The equation is in vertex form:
f = a(x -h)² +k . . . . has vertex (h, k)
The x-coordinate of the vertex can be read from the equation: 4. The vertical line with that x-coordinate is ...
x = 4
__
<u>For h(x)</u>
The vertex is the point where the graph reaches a maximum, (-2, 2). The vertical line with that x-coordinate is ...
x = -2
The vertical distance from the data points to the line are called the residuals.
The given expression is 2x-3 .
So when x =1, we will get 2(1)-3 = 2-3 =-1
When x=2, we will get, 2(2) -3 = 4-3 =1
When x=3, we will get 2(3)-3 = 6-3=3
When x=4, we will get 2(4)-3 = 8-3=5
So the required result of the expansion is -1+1+3+5=8
Correct option is the second option .
