Can anyone do his really quick I’m being timed and need this done very fast

I'm pretty sure your answer will be 23!

Step-by-step explanation:

Because you will have to isolate the variable, so you will subtract x from both sides, leaving x=2+21. 2+21 is 23, so your equation is x=23!

Please mark brainliest!

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
