Answer:
Step-by-step explanation:
#1
- Yes, it is function
- x-values are unique and each has one corresponding y-value
#2
- No, it is not a function
- x-values are repeated with different y-value: (13, 4) and (13, -4)
#3
- Yes, it is a function
- If you put a vertical line, there will always be one intersection with the graph
#4
- Yes, it is a function
- This will produce a parabola which is a graph of a normal function with unique x-values and corresponding y-values
Answer:
y = -4x+15
Step-by-step explanation:
y=x/4+5 may be presented as y = 1/4 x + 5, where a=1/4, b=5
swapping numerator and denominator and inserting an opposite sign in a=1/4, we have:
1/4 --------> 4/1 -------> -4/1 = -4
y = -4x+n
Point (2,7) means that x=2, y=7 substitute it to the equation y=-4x+n, calculate "n":
7=-4*2+n ------> 7=-8+n -------> 7+8 = n -------> 15=n
substituting n=15 to the equation y=-4x+n, we get finally y=-4x+15
