hope helped and that is understandably sure
Answer:
- x = 4 is the only real zero
Step-by-step explanation:
<u>Find the zero's of f(x)</u>
- 2x³ - 12x² + 20x - 16 = 0
- x³ - 6x² + 10x - 8 = 0
- x³ - 4x² - 2x² + 8x + 2x - 8 = 0
- x²(x - 4) - 2x(x - 4) + 2(x - 4) = 0
- (x - 4)(x² - 2x + 2) = 0
- (x - 4)(x² - 2x + 1 + 1) = 0
- (x - 4)[(x - 1)² + 1] = 0
- x - 4 = 0 ⇒ x = 4, we already know this
- (x - 1)² + 1 = 0 ⇒ (x - 1)² = - 1, no real solution as the square is never negative

3x2=6
The exponential function is given by y = 46797(0.93)ˣ
<h3>
Exponential function</h3>
An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let n(x) represent the number of nesting sites, x years since 2001, hence, from table:
At (1, 46125):
46125 = ab¹ (1)
At (7, 27691):
27691 = ab⁷ (2)
Hence:
a = 46797, b = 0.93
The exponential function is given by y = 46797(0.93)ˣ
