Answer 2

\[f(x)=-x^2-10x\] is a quadratic function with a negative a-coefficient. Hence, its graph is ∩ shaped parabola.

1) Translation of a graph by 5 units downward is a subtraction of 5 from f(x). So we have \[-x^2-10x-5\]

2) A vertical stretch by a factor of 6 is multiplication by positive 6. Hence, \[6(-x^2-10x-5)=-6x^2-60x-30\]

3)Since parabola is symmetrical relevant to the y-axis, we consider a reflection in the x-axis of the graph, which is just multiplication by -1. Hence, \[g(x)=6x^2+60x+30\]

(I hope this helps. Good luck on your assignment or whatever.)
