Q. y=(x−2)(x+8)The given equation represents a parabola in the xy-plane. Which of the following equivalent forms of the equation displays the y intercept of the parabola as a constant or coefficient?Choose 1 answer:(A) y=x2+6x−16(B) y=(x+3)2−25(C) y+24=(x+2)(x+4)(D) y+25=(x+3)2
Expand quadratic equation: Expand the given quadratic equation to find the y-intercept.The y-intercept occurs when x=0. To find the y-intercept in the equation, we need to have the equation in standard form, which is y=ax2+bx+c, where c is the y-intercept.y=(x−2)(x+8)y=x2+8x−2x−16y=x2+6x−16
Compare with answer choices: Compare the expanded form with the answer choices.We have found that the expanded form of the given equation is y=x2+6x−16. Now we need to compare this with the answer choices to see which one matches and shows the y-intercept as a constant or coefficient.(A) y=x2+6x−16(B) y=(x+3)2−25(C) y+24=(x+2)(x+4)(D) y+25=(x+3)2
Identify correct answer: Identify the correct answer choice.The correct answer choice will be the one that matches the expanded form we found in Step 1 and clearly shows the y-intercept as a constant or coefficient. From the answer choices, we can see that choice (A) matches our expanded form and displays the y-intercept −16 as a constant.
