An exponential function is expressed in the form y=axb^x. the relation represents a growth when and a decay

answer 1:

select a value -
b> 1
0 b is positive
a> 1
0 a is positive
a is negative

answer 2:

select a value -

b> 1
0 b is positive
a> 1
0 a is positive
a is negative

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.

if 0 < b < 1.  It is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form The relation represents a growth when  b >1 and a decay when 0<b<1.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
