What are the differences between an (Algebraic) equation and expression?

lara31 [8.8K]

Hello!

An equation has an (=). They equal something. For example, 1+1=2 is an equation.

An expression does not have an equal sign. For example, 2 or 1+3 are both expressions. They have no equal sign.

I hope this helps!

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>

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