Question

Equation A matches graph __ because …….I need some help on this

Answer 1

Answer:

The function A is given below as

$y=x^2-6x+8$

Using a graphing tool, we will have the graph be

Hence,

Equation A matches graph 3 because the x-intercepts are on the positive x-axis and it has a y-intercept of 8(on the positive y-axis)

Step 2:

Equation B is given below as

$y=(x-6)(x+8)$

Using the graphing tool, we will have the graph as

Hence,

Equation B matches graph 4

The x-intercepts cuts at the negative x and positive x-axis and the y-intercepts is on the negative y-axis

Step 3:

Equation C is given below as

$y=(x-6)^2+8$

Hence,

Using a graphing calculator, we will have the graph as

Hence,

Equation C matches Graph 1, because its vertex is (6,8) and it has a y-intercept on the positive y-axis
