Answer:

-8

Step-by-step explanation:

Replace the x in f(x) = 2 • 2x with -2

f(-2) = 2 × 2 × (-2) ➡ f(-2) = -8

Answer:

See below

Step-by-step explanation:

<h3>Graphing:</h3>

we are given two functions

$\displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}$

where f(x) is a linear function and g(x) is a quadratic function

we want to figure out the solutions of the function

let's graph f(x):

the Black-table is attached

let's graph g(x):

the picture is attached

hence, the graph should be

the graph is attached

<h3>solutions stating:</h3>

so we need solution(s) which satisfy(ies) the both functions

in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)

hence,

x={-1,3}

Answer: 6 $\sqrt{2}$

Step-by-step explanation: why the process of elimination is because 9 is sticking like a sore thumb and the last one is too big the first one and the third one are similar but the third one has a square root of 3 so it would be THE FIRST ONE.

Y=-4x-5 and y=-4x+1 Many solitions, one solution, or no solution

GuDViN [60]

There will be no solutions because the lines have the same slope (-4) meaning they are parallel to each other and will not cross.

Hope this helps!!
