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:
10(x-3)
Step-by-step explanation:
Since 0 < y < 1.5, hence the coordinate (1,1) is a solution
<h3>A solution to the system of inequality</h3>
Given the following inequality expression
y>0
y< 2.5x - 1
Wee are to check if (1, 1) is a solution to the systen of equation
If x = 1
y < 2.5(1) - 1
Y < 2.5 - 1
y < 1.5
Since 0 < y < 1.5, hence the coordinate (1,1) is a solution

Answer:
(a)
(b)
(c)
the cost of 8 people is $116
(d)
Graph is attached
Step-by-step explanation:
we are given
It costs $145 for 10 people to attend a concert
(a)
Number of people =10
Total cost =145
now, we can find constant proportionality
k= ( total cost)/(number of people)
(b)
Let's assume
cost is C
number of people as x
so, we can set equation as
now, we can plug value
(c)
we can plug x=8
C=116
So,
the cost of 8 people is $116
(d)
we can draw graph
