Step-by-step explanation:
Answer:
f ( - 2 ) = - 12
Step-by-step explanation:
f ( - 2 ) = - 3 ( -2 )^2
then you do the exponent first so
- 3 ( 4 )
now you multpily the - 3 and 4
you get - 12
Answer:
<h3>
ln (e^2 + 1) - (e+ 1)</h3>
Step-by-step explanation:
Given f(x) = ln and g(x) = e^x + 1 to get f(g(2))-g(f(e)), we need to first find the composite function f(g(x)) and g(f(x)).
For f(g(x));
f(g(x)) = f(e^x + 1)
substitute x for e^x + 1 in f(x)
f(g(x)) = ln (e^x + 1)
f(g(2)) = ln (e^2 + 1)
For g(f(x));
g(f(x)) = g(ln x)
substitute x for ln x in g(x)
g(f(x)) = e^lnx + 1
g(f(x)) = x+1
g(f(e)) = e+1
f(g(2))-g(f(e)) = ln (e^2 + 1) - (e+ 1)
The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.
<h3>What is Internal Validity? </h3>
Internal validity can be described as the extent that a particular study can bring about the establishment of a trustworthy cause-and-effect relationship which can be set between the treatment as well as the outcome.
In conclusion, Internal validity let us understand that a study can makes it possible to eliminate alternative explanations as regards finding, hence The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.
