Step-by-step explanation:
<span>Evaluate ƒ(–3) for ƒ(x) = –5x2 + 2x –1.
</span>ƒ(x) = –5x2 + 2x –1
First, Substitute x by -3 in the formula of the function and calculate as follows.
ƒ(-3) = –5x2 + 2x –1
Apply the Order of Operations.
ƒ(-3) = –5(-3)^2 + 2(-3) –1
Simplify
ƒ(-3) = –5(9) + 2(-3) –1
ƒ(-3) = –45 -6 –1
ƒ(-3) = -52
Therefore, The function of ƒ(–3) for ƒ(x) = –5x2 + 2x –1 is -52
Answer:
122.5
Step-by-step explanation:
Let the student normal score be 100
In the beginning score increased by 40%
Hence score at the beginning =100+40 = 140%
Now before end score decreased by 25%
Decrease = 25% of 140 = 35
Hence score at the end of month = 140-35 = 105
Average score for the month
= Total of scores of end and beginning month /2
=
