What is the equation for g, which is f(x) = 2x2 + 3x − 1 reflected across the y-axis? Group of answer choices g(x) = −2x2 − 3x −
Sergio [31]

Answer:

g(x) = 2x^2 - 3x - 1

Step-by-step explanation:

Given

f(x) = 2x^2 + 3x - 1

Required

Determine g(x), if f(x) is reflected across the y axis

<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>

<em />

In other words,

g(x) =  f(-x)

Calculating f(-x)

f(-x) = 2(-x)^2 + 3(-x) - 1

f(-x) = 2x^2 - 3x - 1

Substitute g(x) for f(-x)

g(x) = 2x^2 - 3x - 1

<em>Hence;</em>

g(x) = 2x^2 - 3x - 1

Find f(-3) for f(x) = 4(2)^x.<br> ОА. 1/8<br> O B. -32<br> O C. -24<br> OD. 1/2
Ipatiy [6.2K]

Answer:

D

Step-by-step explanation:

using the rule of exponents

a^{-m} = \frac{1}{a^{m} }

substitute x = - 3 into f(x)

f(- 3) = 4((2)^{-3} = 4 × \frac{1}{2^{3} } = 4 × \frac{1}{8} = \frac{1}{2}
