Answer:
a=
15
b=1/3
Step-by-step explanation:
- key rule: see the graph carefully to get the following identified points.
- from the given graph, it can be seen that, the curve passes through (0,15)
- by substituting this point in y=a*(b)^x,
15=a*(b)^0
15=a
- it can also be seen that the curve passes through (1,5)
- by substituting this point in y=a*(b)^x,
5=a*b
5=15*b ( since, we have found that a=15 from the before steps)
- dividing both the sides by 15,
5/15=b=1/3
a=
15
b=1/3.
It is linear. So A is the answer.
The plot of the graph y = –1.5(4)^x is shown below of which its domain and range exist on all real values
<h3>Exponential equation</h3>
The standard exponential function is expressed as y = ab^x
where
- a is the base value
- x is the exponent
The exponential function shows an increase along the y-axis and towards the x-axis
According to the equation, we are to plot the graph y = –1.5(4)^x of which its domain and range exist on all real values
