A function is shown f(x)=x^2+2x-1 which graph represents the function

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.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
