Answer:

C. 2(2x + 3)(2x - 3)

Step-by-step explanation:

$8 {x}^{2} - 18 \\ = 2 \times 4 {x}^{2} - 2 \times 9 \\ = 2(4 {x}^{2} - 9) \\ = 2 \{( {2x})^{2} - ( {3)}^{2} \} \\ = 2(2x + 3)(2x - 3) \\$

Which equation, when graphed, has x-intercepts at (-1,0) and (-5,0) and a y-intercept at (0, -30)?

Vladimir [108]

If a function has roots -1 and -5, it must be in the form

$f(x)=a(x+1)(x+5)$

We can fix the coefficient a by imposing the passing through (0,-30):

$f(0)=-30=a(1)(5)\iff a=-6$

So, the function is

$f(x)=-6(x+1)(x+5)$

The question is asking you which shape is the same shape as the shape displayed with the question. The shape could be bigger, smaller, flipped around, or any other different way, but it has to be the same shape.

The answer is B.

The reason why B is your answer because the shape is the same, but it's just that it is smaller. The shapes scale is just smaller, but it's still the same shape. and flipped around.
