Which graph represents exponential decay ?

Out of those 2, the first one shows decay as it goes down from left to right.

graph 1 represents exponential decay .

Step-by-step explanation:

Given : exponential graphs .

To find  : Which graph represents exponential decay .

Solution : WE have given two  exponential graph :

we can see from graph 1 , As the values on x axis increases values on y axis decreases But in graph 2 both the values on x axis and y axis are increases simultaneously.

Therefore, graph 1 represents exponential decay .

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
