F(x)=-5x+7, what is x when f(x)= -23?
Ask: F(x)=-5x+7, what is x when f(x)= -23?
EVALUATING FUNCTION
Answer: 122
Solution:
F(x) = -5(-23) + 7
F(x) = 115 + 7
F(x) = 122
• When a function F is defined by y= f(x), then x is called the independent variable. Any element of the domain can be chosen as a value of the independent variable. The resulting value determines the corresponding value of the dependent variable.
• The value of the dependent variable y= f(x) that correspondents to a specific value of an independent variable x is found by substituting x into the function rule, then, simplifying the resulting expression. Such process is called evaluating a function:
Steps:
1. Write the given function
2. Replace every x in the function rule g(x) with the given replacement value
3. then simplify the resulting numerical expression
4. Write the final answer

If f(x)=6x-4, what is f(x) when x=8?
Ask: If f(x)=6x-4, what is f(x) when x=8?
f(x) = 6x-4
f(8) = 6(8) – 4
f(8) = 48 – 4
f(8) = 44
If f(x) = x/2 + 8, what is f(x) when
Ask: If f(x) = x/2 + 8, what is f(x) when x = 10?
Answer: 13
Step-by-step explanation:
f(x) = x/2 + 8
f(x) = 10/2 + 8
f(x) = 5 + 8
f(x) = 13
the function f(x) varies directly with x and f(x)=4 when
Ask: the function f(x) varies directly with x and f(x)=4 when x=12 what is the value of f(x) when x=60
EQUATION: f(x) = kx
4 = k(12)
[tex]frac{4}{12}[/tex] = [tex]frac{12k}{12}[/tex]
k = [tex]frac{1}{3}[/tex]
f(x) = [tex](frac{1}{3})[/tex]x
f(x) = [tex](frac{1}{3})[/tex](60)
f(x) = 20 <== ANSWER
If f(x) = 6x – 4, what is f(x) when
Ask: If f(x) = 6x – 4, what is f(x) when x = 8?
Substitute x with 8
6(8)-4
48-4 = 44
Answer:
44 ^-^
Solution:
f(x)=6x-4
f(8)=6(8)-4
f(8)=48-4
f(8)=44
If f(x) = 5x + 40, what is f(x) when
Ask: If f(x) = 5x + 40, what is f(x) when x = –5?
f (x)= 5 (-5) +40
f (x)= -25+40
f (x)=15
if f(x) = 5x + 40, when x = -5
f(x) = 5(-5) + 40
f(x) = -25 + 40
∴ f(x) = 15
If f(x) = + 8, what is f(x) when x
Ask: If f(x) = + 8, what is f(x) when x = 10?
f(x) = x + 8
f(10) = 10 + 8
f(10) = 18
ANSWER: f(10) = 18
What is f(x) + f(x) + f(x)? when f(x)=x2
Ask: What is f(x) + f(x) + f(x)? when f(x)=x2
f(x) + f(x) + f(x)?
now, we substitute the f(x) to x^@
x^2 + x^2 + x^2
ANSWER ==> 3x^2
remember, if there’s no number at the side of the variables, it is considered as 1.
Not only you can get the answer of what is f(x) when x, you could also find the answers of F(x)=-5x+7, what is, If f(x) =, If f(x) =, What is f(x), and What is the.
