Answer:
B' - (3,1)
C' - (3,8)
D' - (6,-1)
Step-by-step explanation:
The function is decreasing from x= -3 to x= -1
Answer:
f(6) = 2
Step-by-step explanation:
Since y is a function of x, that is y = f(x), f(6) implies that we shall be evaluating the value of y when the value of x is 6.
To do this we shall draw a vertical line, x = 6 and check where this line intersects with the graph of the function f(x)
The vertical line x = 6 intersects with the graph of the function f(x) on the horizontal line y = 2. The function f(x) assumes the value 2 for values of x between 4 and 8. Therefore, f(6) = 2
4x+3y= 9
3y=9-4x
Y= (9-4x)/3
Y= 3-4/3x
Therefore, the slope is -4/3 which makes answer choice #3 correct.
Hope this helps!
