Given:
The function is

To find:
The range value if the domain value is 1.75.
Solution:
Domain is the set of input values and range is the set of output values.
Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.
Substitute x=1.75 in the given function.



Therefore, the required range value is 4.5.
Answer:
A. a is where performance is minimal
Step-by-step explanation:
b is representing peak performance.
So we have to simplify this equation:
4x+5-10+3x=57
Add like terms:
7x-5=57
Then add 5 to both sides:
7x=62
x=62/7
35
“Negative times a negative is a positive”
Answer:
y = -0.6x +3
Step-by-step explanation:
equation of the line through point (3, 1.2) and y-interecept of 3
y= mx+b
m is the slope and b is thhe y-intercept
y = mx + 3
between points (3, 1.2) and (0,3) the slope is
m= (y2-y1)/ (x2-x1) = (1.2-3) / (3-0) = -1.8/3 = -0.6
y = -0.6x +3
