Answer:
Graph (2), top right.
Step-by-step explanation:
Given function is f(x) = x² + 2x - 1
f(x) = x² + 2x + 1 - 2
f(x) = (x + 1)² - 2
From this standard equation of a parabola,
Vertex → (-1, -2)
Axis of symmetry → x = (-1)
y-intercept → y = (-1)
Since coefficient of maximum degree term (x²) is positive so, parabola is opening upwards.
From the given choices, second option (top row right) is the answer.

Answer:
99 038.52 USD
Step-by-step explanation:
In order to solve this question we have to use the compound interest formula
A = P*(1+i)ˆn
A: final amount including principal
P: principal amount
i: interest per year
n: total number of years
A = 40000 (1+0.12)ˆ8
A = 99 038.52 USD
