k = - 2 is excluded from the domain
the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that k cannot be
solve k + 2 = 0 ⇒ k = - 2 ← excluded value
Suggartits it’s easy the answer is 3Baconatore 2 frosty free points bby
So the vs eliminate each other which leaves the ws and the 1,7. Then you add the 2 ws to get 2w and then add the numbers to get 2w=8, then divide 8 by 2 and you get w=4
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
