Answer:
a = 8, b = 
Step-by-step explanation:
Given the exponential function
f(x) = a
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a [
 [  = 1 ] , then
 = 1 ] , then
a = 8
f(x) = 8
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
 = b² , that is
 = b² , that is
b² =  ( take the square root of both sides )
 ( take the square root of both sides )
b =  =
 = 
Thus 
f(x) = 8
 
        
             
        
        
        
Answer:
 The length of the rectangle (l) = 3 feet
 The width of the rectangle (W) =  10 feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that the width of the rectangle  = (x+1) feet</em>
<em>Given that the length of the rectangle = ( x-6) feet</em>
<em>The area of the rectangle = 30 square feet</em>
<u><em>Step(ii):-</em></u>
We know that the area of the rectangle
                 = length ×width
     30   = ( x+1)(x-6)
     30   = x² - 6x + x -6
⇒ x² - 5 x - 6 = 30
⇒ x² - 5 x - 6 - 30 =0
⇒ x² - 5 x - 36 =0
  x² - 9 x +4x - 36 =0
    x (x-9) +4 ( x-9) =0
    ( x+4 ) ( x-9) =0
      ( x+4 ) =0 and  ( x-9) =0
      x =-4 and x =9
<u><em>Step(iii):-</em></u>
we have to choose x =9
      The length of the rectangle (l) =  x-6 = 9-6 =3
       The width of the rectangle (W) =  x+1 =  9 +1 = 10
<u><em>Final answer:-</em></u>
 The length of the rectangle (l) = 3 feet
 The width of the rectangle (W) =  10 feet

Correct Answer:
Option 3: <span>The quadratic function has two distinct real zeros.
The function is quadratic, therefore it can have only 2 zeros. The knowledge of x-intercepts is needed to determine the zeros, y-intercepts has nothing to do with the zeros of a function. The given function has 2 unique x-intercepts, so according to the fundamental theorem of algebra, this function has 2 distinct real roots as number of distinct real roots are equal to the number of x-intercepts. Therefore, option 3 is the correct answer. </span>
