Answer:

Step-by-step explanation:

Where are the given answer choices? Please note that ^2 cannot stand alone; you meant x^2.

If f(x)=x^2-4x+3, f(-3) is found by subbing -3 for x in f(x)=x^2-4x+3:

f(-3) = (-3)^2 - 4(-3) + 3

= 9 + 12 + 3

= 24

$\huge{ \boxed{ \bf{ \red{Problem:-}}}}$

<h3>Solve for x: 3/2 + 1/2x =2x</h3>

$\huge{ \boxed{ \bf{ \red{Solution:-}}}}$

$\bold{ \frac{3}{2} + {\frac{1}{2} x = 2x}}$

$\bold{ ⇒\frac{3}{2} + {\frac{x}{2} = 2x}}$

$\bold{⇒\frac{3 + x}{2} = 2x}$

$\bold{⇒3 + x = 2(2x)}$

$\bold{⇒3 + x = 4x}$

$\bold{⇒3 = 4x - x}$

$\bold{⇒ \frac{3}{3} = x}$

$\bold{ \therefore{x = 1}}$
