Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Let analyse each table

  • Table A

X            Y              ΔY/ΔX

1             5               xxxxxx              

2            11            11 - 5 = 6            

3           29             29 - 11 = 18          

4           83             83 - 29 = 54

.....................

We can see that, [ ΔY/ΔX ]   increases at the fastest rate out of all functions, so it must be exponential function

  • Table B

X            Y                 ΔY/ΔX            Δ^2Y/ΔX^2          

0             5                 xxxxxx              xxx              

1              7                 7 - 5 = 2            xxx            

2             13               13 - 7 = 6           6-2 = 4        

3             23              23 - 13 = 10       10-6 = 4

..............................

It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values

  • Table C

X            Y                 ΔY/ΔX                      

3             20               xxxxxx                  

6             18                 2 / 3

9             16                 2 / 3                    

15            12                 2 / 3      

..............

It is a linear because ΔY/ΔX = 2/3 are constant for all values

Consider the quadratic equation. x^2=4x-5. How many solutions does the equation have?
Vesna [10]

x^2=4x-5
subtract 4x from both sides
x^2-4x=-5
add 5 to both sides
x^2-4x+5=0

input into quadratic formula which is x=\frac{-b+ \sqrt{b^2-4ac} }{2a} or \frac{-b- \sqrt{b^2-4ac} }{2a}

si ax^2+bx+c
so a=1
b=-4
c=5
input
\frac{-(-4)+ \sqrt{-4^2-4(1)(5)} }{2(1)}=\frac{4+ \sqrt{16-20} }{2(1)}=\frac{4+ \sqrt{-4} }{2}=\frac{4+ \sqrt{4} times \sqrt{-1} }{2} \frac{4+2 times  \sqrt{-1}  }{2}=  \frac{6 times  \sqrt{-1}  }{2}=3 times  \sqrt{-1} [\tex][\tex]\sqrt{-1} representeds by 'i' so solution is 3i

then if other way around then wyou would do
\frac{-(-4)- \sqrt{-4^2-4(1)(5)} }{2(1)}=\frac{4- \sqrt{16-20} }{2(1)}= \frac{4- \sqrt{-4} }{2} =\frac{4- \sqrt{4} times \sqrt{-1} }{2}= \frac{4-2 times \sqrt{-1} }{2}=\frac{2 \sqrt{-1} }{2}= \sqrt{-1} and [\tex]\sqrt{-1} [/tex] is represented by i


the solution is x=3i or i (i=\sqrt{-1})
but i is not real, it is imaginary so there are no real solution so the answer is C
