(-4⁹)²

= -4⁹×²

= -4¹⁸

=( -4)¹⁸

(4-³)-³

= 4-³ × -³

All real numbers greater than or equal to -3

Step-by-step explanation:

we know that

The curved line could be a vertical parabola opening upwards with vertex at (2,-3)

The vertex is a minimum

The y-intercept is the point (0,1)

The x-intercepts are the points (0.25,0) and (3.75,0)

The domain is the interval -----> (-∞,∞)

All real numbers

The range is the interval ----> [-3,∞)

All real numbers greater than or equal to -3
