Answer:
x = 3
Step-by-step explanation:
calculate the slope using the slope formula and equate the result to - 2
m =
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (x, 8)
m = =
= - 2, thus
- 2(x - 5) = 4, that is
- 2x + 10 = 4 ( subtract 10 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3
Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:
The domain for this function is given by:
since the natural log is not defined for negative numbers
,
We can calculate some points in order to see the tendency of the graph, we can select a set of points for example and we can calculate the values for f(x) like this
x=5.5
x=6
That represent the x intercept
x=7
x=8
x=9
x=10
And that represent the x intercept
And then we can see the plot on the figure attached.
