Answer:
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
The equation that is a linear function is y = 2x + 1, the correct option is A.
The standard equation of a linear function is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
A function is what correlates a dependent and an independent variable, the range and domain of a function is always defined.
A linear function represents a straight line on the coordinate plane.
Equation 1 is y = 2x +1
Equation 2 is y² = 3x + 1
Equation 3 is : y = 5x⁵ − 1
Equation 4 is y = 4x⁴ -1
The equation that corresponds to the standard equation of a linear function is only equation 1.
The graph can be used to confirm this, the graph shows a linear function, with slope of 2 and y intercept of 1.
