Appears that you've overlooked the need to share the possible answer choices.
f(x)=x^2x-1 has a parabolic graph with vertex at (0,-1). This is also the location of the vertex. Because the coefficient of x^2 is positive, this graph opens up. Thus, the smallest possible y value here is -1. The range of this function is
[-1, infinity).
Answer:
The cost of the one word is $30 .
Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
Step-by-step explanation:
Let us assume that the number of words in the ad be x.
As given
Mr.grant spent $8.40 to place an ad in the newspaper.
This price included one time fee of $6.00 plus $0.08 per word.
Than the equation becomes
8.40 = 6 .00 + 0.08x
Simplify the above
8.4 = 6 + 0.08x
8.4 - 6 = 0.08x
x = $30
Therefore the cost of the one word is $30 .
Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
