Which is one of the transformations applied to the graph of f(x)=x^2 to change it into the graph of g(x)=4x^2+24x*30?

AfilCa [17]

Answer:

Changing g(x) to this form: a(x-h) + k, we have:

g(x) = 4 (x+3)^2 - 6

Comparing this to the original equation, f(x) = x^2, we have the following transformations:

The graph is widened.

The graph is shifted left 3 units.

Answer:

113 $m^{2}$

Step-by-step explanation:

top rectangle = l x w = 6 x 13 = 78

Answer:

$\large\boxed{x\leq-27}$

Step-by-step explanation:

$\dfrac{x}{-9}\geq3\qquad\text{change the signs}\\\\\dfrac{x}{9}\leq-3\qquad\text{multiply both sides by 9}\\\\9\!\!\!\!\diagup^1\cdot\dfrac{x}{9\!\!\!\!\diagup_1}\leq(-3)(9)\\\\x\leq-27$
