PLZ HELP ME 100 POINTS AND BRAINLIST IF YOU ANSWER ALL OF THEM PLZ 1)Kai's Kites decided to advertise on billboards around town and track the relationship between the number of billboard advertisements they posted and the number of kites they sold. This table gives the total number of billboards advertisements they bought compared to the total number of kites they sold. The data can be modeled by a quadratic function.

What function best models the data?

y=0.15x^2+119

y=2.5x^2+15.4x

y=2.5x^2+102x+15.4

y=0.15x^2−10.6x+119

2)The graph of f(x)=x2 is shown.

Use the parabola tool to graph the function g(x)=(14x)2.

To graph a parabola, first plot the vertex then plot another point on the parabola.

3)Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) .

Which pair of functions could have been used to create the graphs of g(x) and h(x)?

h(x)=x2+12 and ​g(x)=x2​

h(x)=(x+12)2 and ​g(x)=x2​

h(x)=x2−12 and g(x)=x2

h(x)=(x−12)2 and ​g(x)=x2

4)The length of a rectangle is 3 m greater than its width. The area of the rectangle is 154 m². This situation can be expressed by the equation w2+3w−154=0.

What is the width of the rectangle?
