Answer:

The answer to all of those questions would be x=-1.8

Step-by-step explanation:

7x(x + 1.8) = 0 - Distribute through the Parenthesis -

7x^2 + 12.6x = 0

x(7x + 12.6) = 0

x = 0

7x + 12.6 = 0

7x = -12.6

x = -12.6/7

x = -1.8

so x = 0 or x = -1.8

Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis?

aleksley [76]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

In a reflection across the y-axis the y-coordinate remains the same, but the x-coordinate is transformed into its opposite

we have

$f(x)=2(0.4)^{x}$

The reflection of f(x) across the y-axis is equal to the function g(x)

$g(x)=2(0.4)^{-x}$
