Answer:
f(x)=1
Step-by-step explanation:
All you do is substitute -1/2 for x in f(x), so
f(x)=4(-1/2)+3
f(x)=(-2)+3
f(x)=1
<span>B. f(x) = x^2 + 6x - 7
All you have to do is foil

Replace X with 3 and simplify. The answer you would get is 11.
By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).
