The equation that represents the linear function is y =32x
<h3>What is a linear function?</h3>The question is an illustration of a linear function; a linear function is a function that has a constant rate/slope
A linear function is represented as:
Where
- m represents slope
- c represents the y-intercept
The slope is calculated as:
So, we have:
The linear equation is then calculated as:
So, we have:
Hence, the equation that represents the linear function is y =32x

Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= -
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
= -
= - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )
