just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
Answer:
look at the explanation
Step-by-step explanation:
in order to create a f(-2) you would need to know either a table of values or an equation to plug values into . . .saying a function of -2 does not really help, sorry
Answer:
c) Population parameter or Population statistic
Step-by-step explanation:
<u>Population</u>:-
<em>The totality of observation with which we are concerned , whether this number be finite or infinite is called population</em>
<u>Sample </u>:
A sample is subset of a Population
Given data the USA today internet poll is called Population
<em>Given data 73 percent of readers are satisfied with their lives.
</em>
<em>This is called Population parameter.</em>
Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
