Answer:

$f(x) = {x}^{2} + 4x - 1 \\ f( - 1) = {( - 1)}^{2} + 4( - 1) - 1 \\ = - 4 \\ { \boxed{f( - 1) = - 4}} \\ \\ f(1) = {(1)}^{2} + 4(1) - 1 \\ = 4 \\ { \boxed{f(1) = 4}}$

Need help with this

Answer:

First off, who is Landon Long? Nevermind.

Step-by-step explanation:

So to create equal fractions, you must multiply both the denominator and numerator by the same number.

Example:

$\frac{1}{2} *\frac{3}{3} =\frac{3}{6} =\frac{1}{2}$

What I see is that maybe you need to use the pictures to multiply the fractions by another fraction with the same numerator and denominator to create an equivalent fraction!

Sorry, might be wrong... :(

Anyways, hope this helps!

P.S. Stay Safe
