Hello :
f(x) = (x − h)2 + k: a <span> vertex of( 2, 3)
h=2 and k=3</span>
Answer: periodic investment APEX
Step-by-step explanation:
Y = -2/5x - 11 is the equations
The C(x) equation is a parabola with a squared "x" and a positive leading term coefficient, meaning, is a vertical parabola and it opens upwards
the lowest point, or lowest cost value, it reaches, is the U-turn point, or vertex

so, the lowest cost is at
The graph that represents the given linear function is attached below.
We are given a function. A function connects an input with an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. The equation is linear in nature. It represents a straight line. The equation is given below.
(y - 4) = (4/3)(x - 2)
A line's general equation in slope-intercept form is y = mx + c. We will convert the given equation into this form.
y - 4 = (4/3)x - 8/3
y = (4/3)x - 8/3 + 4
y = (4/3)x + 4/3
The slope of the given equation is 4/3. The y-intercept for the given equation is 4/3.
