Answer 1

1. Which of the following best describes the graph of f(x) = x2 + 3x - 10?

Minimum at (1.5, -12.25) with intercepts at (5, 0) and (-2, 0)

Minimum at (-1.5, -12.25) with intercepts at (-5, 0) and (2, 0)

Minimum at (-3.5, -2.25) with intercepts at (-5, 0) and (-2, 0)

Minimum at (3.5, -2.25) with intercepts at (5, 0) and (2, 0)



2. Identify the factors of x2 + 25y2.

(x + 5y)(x + 5y)

(x + 5y)(x - 5y)

(x - 5y)(x - 5y)

Prime

Answer 2

2. Prime

Answer 3

(x^2 - 3x - 10) / ( x^2 - 4) = [ ( x - 5 ) ( x + 2 ) ] / [ ( x - 2 ) ( x + 2 ) ]

S0, f(x) = y = (x - 5 ) / ( x - 2 ) if x is not equal to -2.

So y = ( x - 2 - 3 ) / ( x - 2 ) and y is not defined at x = -2

= 1 - 3 / ( x - 2 )
So ( y - 1 ) ( x - 2 ) = - 3

Shifting origin to ( 2, 1), y'x' = - 3 and y' not defined for x' = - 4
This is the graph of rectangular hyperbola.
Draw the graph with a puncture at x' = - 4 and shift the origin back.
