Hey there :)
( 2x⁵ - 3x⁴ + x² + 5x + 7 ) - ( - 4x⁵ - x⁴ - 3x² - 5x + 2 )
Let us combine like-terms
2x⁵ - ( - 4x⁵ ) - 3x⁴ - ( - x⁴ ) + x² - ( - 3x² ) + 5x - ( - 5x ) + 7 - 2
Minus and minus becomes plus
2x⁵ + 4x⁵ - 3x⁴ + x⁴ + x² + 3x² + 5x + 5x + 7 -2
6x⁵ - 2x⁴ + 4x² + 10x + 5
Your answer will be option A) 6x⁵ - 2x⁴ + 4x² + 10x + 5
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.
Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.
On this exercise is given that a triangle with vertices (-2,1), (8,4), and (3,0) was dilated by a scale factor of four, and it is asked to find the vertices of the image of the triangle after the dilation occurred.
Pre-image Image
(-2,1) -- (-2*4,1*4) -- (-8,4)
(8,4) -- (8*4,4*4) -- (32,16)
(3,0) -- (3*4,0*4) -- (12,0)
The coordinates representing the vertices of the triangle's image are (-8,4), (32,16), and (12,0); meaning that the ordered pair which is not a coordinate for a point in the triangle's image is (2,1).

The discriminant of the function will be negative.
Option C is true.
What is mean by Discriminant?
The discriminant of the function describe the roots of the function.
Which is defined as for a quadratic equation ax² + bx + c = 0;
D = b² - 4ac
Given that;
The graph of the function is shown in attached figure.
Now,
When the graph has any x - intercepts then the function has a real roots, so the discriminant must be positive.
Here, From the given graph of the function,
We have the function which have no any x - intercept, that is do not cross the x - axis at any point.
Hence, The graph of the function has no real roots.
Thus, We can say that;
The discriminant must be negative.
Therefore, The discriminant of the function is negative.
