Answer:
1.8 and 14.3
Step-by-step explanation:
Our equation is a quadratic equation so we will use the dicriminant method
- Let Δ be our dicriminant
- a=1
- b= -16
- c= 25
- Δ= (-16)²-4*25*1=156≥0
- so we have two solutions : x and y
- x= (16-
)/2= 1.7555≈ 1.8 - y=(16+)/2=14.244≈ 14.3
This is a method of substituting values into a given function. The value of the function f x is 7.6 is 3.8
<h3>Functions and values</h3>
Given the following function expressed as:
f(x) = 1/2(x)
We are to determine the value of f(7.6). Substitute x = 7.6 into the function as shown:
f(7.6) = 1/2(7.6)
f(7.6) = 7.6/2
f(7.6) = 3.8
Hence the value of the function f x is 7.6 is 3.8
