Consider the quadratic function f(x)=−x^2+4x+12
777dan777 [17]
<h2>Answer:</h2>
  • The smallest x-intercept is x= -2
  • The largest x-intercept is x=  6
  • The y-intercept is y= 12
<h2>Step-by-step explanation:</h2>

We are given a function as follows:

y=f(x)=-x^2+4x+12

The x-intercept of a function is the value of x where the function is equal to 0.

i.e.

y=f(x)=0

-x^2+4x+12=0

i.e.

x^2-4x-12=0\\\\x^2-6x+2x-12=0

( We used the method of splitting the middle term)

x(x-6)+2(x-6)=0\\\\(x+2)(x-6)=0

i.e.

x=-2\ and\ x=6

Hence, the smallest x-intercept is: x= -2

and the largest x-intercept is: x=6

The y-intercept is the value of y where x=0

i.e. we have:

y=-0^2+4\times 0+12\\\\y=12

Pls help with linear equations!!!
artcher [175]

Answer:

266

Step-by-step explanation:

Let no. of main floor tickets = x

Balcony tickets = x + 100

4(x+100) + 12(x) = 3056

4x + 400 + 12x = 3056

16x = 3056-400

16x = 2656

x = 2656/16

x = 166

No. of Balcony tickets = x + 100 = 166 + 100 = 266
