Answer:
f(x) = x² - 2x - 15
Step-by-step explanation:
∵ The function intersect x-axis at -3 and 5
∴ f(x) = 0 at x = -3 , 5
∵ The form of the quadratic equation is ⇒ ax² + -b/a x + c/a = 0
ax² - b/a x + c/a = 0
Where the sum of its roots is b/a and their multiplication is c/a
∵ a = 1
∵ -3 , 5 are the roots of the quadratic equation
∴ b = -3 + 5 = 2
∴ c = -3 × 5 = -15
∴ f(x) = x² - 2x - 15
Answer:
-1
Step-by-step explanation:
get -3 to the other side of the equation. 2a=-2 so a is -1

just answered this question ;)
Answer:
Local maximum: approx. (1, 8.08), Local minima: approx. (-2, -7.67) and (3, 2.75)
Step-by-step explanation:
Local maxima are the various maxima in the function and the local minima are the various minima in the function. Knowing that, we can deduce that the answer is "Local maximum: approx. (1, 8.08), Local minima: approx. (-2, -7.67) and (3, 2.75)" or C.
