Is the given linear expression a factor if the polynomial?<br><br>f(x) = 2x^3 + x^2 - 5x + 2; x + 2​
Minchanka [31]

Answer:

Yes.

Step-by-step explanation:

Given:  f(x) = 2x^3 + x^2 - 5x + 2; x + 2​

If x + 2 is a factor of f(x),  then , by the Factor Theorem,  f(-2) = 0.

So we check if this is so:

f(-2) = 2(-2)^3 + (-2)^2 - 5(-2) + 2

=  -16 + 4 + 10 + 2

= -16 + 16 = 0.

So Yes x + 2 is a factor.

Determine the scale factor of the function f(x)=3/x
svlad2 [7]
<span>A scale factor is a number which scales, or multiplies, some quantity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor.

Given a function
f(x)=\frac{3}{x}
which is formed from the parent function
f(x)=\frac{1}{x}

The function
</span><span>f(x)=\frac{3}{x}
was obtained from the parent function by multiplying the parent function by 3.

Therefore, the scale factor of the function </span><span>f(x)=\frac{3}{x} is 3.</span>
