Answer:
y = 12 
Step-by-step explanation:
The standard form of the exponential function is
y = a 
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a
( = 1 ), so
a = 12, then
y = 12 
Using (1, 34.8 ) , then
34.8 = 12 
( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12
Answer:
y = -2x
Step-by-step explanation:
It passes through -5, 10 and 5, -10
gradient = Δy/Δx
gradient = -10 - 10 / 5 -- 5
gradient = -20 / 10
gradient = -2
let's use -5, 10 for y = mx + b
10 = -2(-5) + b
10 = 10 + b
b = 10 - 10
b = 0.
the equation of the line is just y = -2x
y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
