Answer:
b) i) Curve A
ii) - 1.75
iii) x = 1 - √5 or x = 1 + √5
Step-by-step explanation:
b) i) We are given a function y = x² - 2x - 3 and the graph of this function is also shown in the side diagram.
The equation can be rearranged to y = (x - 1)² - 4
⇒ (x - 1)² = y + 4
Therefore, this is an equation of a parabola having the vertex at (1,-4) point and its axis is parallel to the positive y-axis.
So, the curve A represents the equation given. (Answer)
ii) Now, at x = 2.5, f(x) = 2.5² - 2 × 2.5 - 3 = - 1.75 (Answer)
iii) When y = 1, then x² -2x - 3 = 1
⇒ x² - 2x - 4 = 0
⇒ (x - 1)² - 5 = 0
⇒ (x - 1)² - (√5)² = 0
⇒ (x - 1 + √5)(x - 1 - √5) = 0
⇒ x = 1 - √5 or x = 1 + √5 (Answer)
Answer:
what is the rest of the equation?
Step-by-step explanation:
<h2><u>Polynomial Function</u></h2>
<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>
To determine the answer, substitute the given value to the function and simplify.
- h(x) = 3x² + 2 - 2x; h(-2)
- h(-2) = 3(-2)² + 2 - 2(-2)
- h(-2) = 3(4) + 2 + 4
- h(-2) = 12 + 2 + 4
- h(-2) = 14 + 4
- h(-2) = 18
