Which equation represents a linear function? equation 1: y = 2x + 1 equation 2: y2 = 3x + 1 equation 3: y = 5x5 − 1 equation 4: y = 4x4 − 1 equation 1 equation 2 equation 3 equation 4

A: y = 2x + 1

Step-by-step explanation:

Alright, let's see.

Equation 1: y = 2x + 1

Equation 2: y^2 = 3x + 1

Equation 3: y = 5x^5 − 1

Equation 4: y = 4x^4 − 1

The moment exponents are involved, the line on the chart becomes all squiggly, and thus not a function, as they're mildly unpredictable. The only equation here that makes sense is Equation 1 (see above).

Let's say, our input number is ten (10).

y = 2*10 + 1

y = 20 + 1

y = 21

Now, our input is four (4).

y = 2*4 + 1

y = 8 + 1

y = 9

Let's try another equation. Equation 2. Our input will be ten (10).

y^2 = 3*10 + 1

y^2 = 30 + 1

y^2 = 31

What to the second power equals 31?

alright so i went off on a tangent there basically but the answer is A

what is the information provided?
