1) The parent function of the function represented in the table
x2-x1=2-1→x2-x1=1, f(2)-f(1)=11-9→f(2)-f(1)=2
x3-x2=3-2→x3-x2=1=x2-x1, f(3)-f(2)=15-11→f(3)-f(2)=4 different to f(2)-f(1)=2
The function is not linear

[f(3)-f(2)]-[f(2)-f(1)]=4-2=2
x4-x3=4-3→x4-x3=1=x3-x2=x2-x1
f(4)-f(3)=23-15→f(4)-f(3)=8
[f(4)-f(3)]-[f(3)-f(2)]=8-4=4 > 2=[f(3)-f(2)]-[f(2)-f(1)]

Answer: The parent function of the function represented in the table is exponential.

2) If function f was translated up 5 units, the f(x) - values would be increased by 5.

3) The points in the table for the transformed function would be:
(1,9+5)=(1,14)
(2,11+5)=(2,16)
(3,15+5)=(3,20)
(4,23+5)=(4,28)
(5,39+5)=(5,44)
Answer: A point in the table for the transformed function would be (2,16)

First differences are 2, 4, 8, 16, which is a geometric sequence. The parent function is not linear (constant first difference) or quadratic (first difference increases by the same amount from one to the next). When the first differences are a geometric sequence, the underlying sequence is a geometric (exponential) sequence.

1st blank: exponential

Translation up adds a constant to each of the f(x) values.

2nd blank: f(x)
3rd blank: increased by 5<span>

For the last blank, you're looking for an (x, f(x)) pair that is translated to (x, f(x)+5).

4th blank: </span><span>(2, 16)</span>

Y=x^2-6x+3 help write the vertex form of the equation
Artist 52 [7]

Answer:

y=(x-3)^2-6

Step-by-step explanation:

y=x^2-6x+3

This is written in the standard form of a quadratic function:

y=ax^2+bx+c

where:

  • ax² → quadratic term
  • bx → linear term
  • c → constant

You need to convert this to vertex form:

y=a(x-h)^2+k

where:

  • (h,k) → vertex

To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:

x=-\frac{b}{2a}

Using your original equation, identify the a, b, and c terms:

a=1\\\\b=-6\\\\c=3

Insert the known values into the equation:

x=-\frac{(-6)}{2(1)}

Simplify. Two negatives make a positive:

x=\frac{6}{2} =3

X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:

y=3^2-6(3)+3

Simplify using PEMDAS:

y=9-18+3\\\\y=-9+3\\\\y=-6

The value of y is -6 (3,-6). Insert these values into the vertex form:

(3_{h},-6_{k})\\\\y=a(x-3)^2+(-6)

Insert the value of a and simplify:

y=(x-3)^2-6

:Done
