Answer: See below
Step-by-step explanation:
A linear line is a straight line. It can be going up, down, vertical, or horizontal. As long as it's a straight line, then it is a linear equation. Graph 1 and 5 are linear.
A quadratic graph is a parabola. It is in the shape of a "U". The "U" can be doing up or down. It can also be more than a parabola. Any x to th epower of a number is also a quadratic graph. Graph 2 and 4 are quadratic graphs.
An exponential graph is a graph that is a number to the power of x. These graphs are also continuous. They go towards infinity. Graph 3 and 6 are exponential.
Answer:
C
Step-by-step explanation:
When x is negative 1/2 ^x becomes 1 / ( 1/2 ^x) meaning it is quite large as x becomes more negative
when x = 0 the value is 1
as x increases from 0 to + inf the value becomes smaller...but never negative
the only graph that fits is C
Answer:
161 million
Step-by-step explanation:
The growth factor over the period from 1990 to 2001 (11 years) is ...
growth factor = (159/154)
Then an exponential equation for the population growth could be ...
p(t) = 154(159/154)^(t/11)
where t is the number of years since 1990.
__
In 2005, the value of t is 15, so the model predicts a population of ...
p(15) = 154(159/154)^(15/11) ≈ 160.86 . . . . million
The population is estimated to be 161 million in 2005.
Answer:
(f * g)(x) has a final product of 16x² + 8x.
Step-by-step explanation:
When you see (f * g)(x), this means that we are going to be multiply f(x) and g(x) together.
<em>f(x)=8x</em>
<em>g(x)=2x+1</em>
Now, we multiply these terms together.
(8x)(2x + 1)
Use the foil method to multiply.
16x² + 8x
So, the product of these terms is 16x² + 8x.
