The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.
The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).
Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).

Option B
Step-by-step explanation:
Step 1 :
Option A does not represent the Venn diagram because it specifies that the triangle does not have 3 vertices which is not true
Step 2 :
Option B is the conditional statement which is represented by the Venn diagram because a triangle has 3 corners or vertices and 3 lines or edges.
Step 3 :
The statement in option 3 and 4 is not represented by the Venn diagram as it is not the definition of a triangle
Answer:
A) what did the student do wrong, explain why they are incorrect
B) Demonstrate and explain the correct way to answer the question.
Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.
<u>3x+8x+20 = 6x+5x+5</u>
<u>11x+20 = 11x+5</u>
<u>She is wrong</u>
Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both
<u>She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be </u>
<u>x=-15 </u>
