Given f(x)=10-2x find f(7)

Answers

Answer 1
Answer:

Answer: -4

Step-by-step explanation: The equation is a simple function having two variables x and y. f(x) can also be written as y.

Therefore, another way to write a function is y = 10-2x.

The question requires you to insert the value of one variable and calculate the other. In this case you have to find the value of function when x=7.

Insert 7 in place of x. So, the equation will look as follows.  

f(x) = 10 - 2*7

f(x) = 10 - 14  

f(x) = -4

Therefore, when x=7 the value of our function f(x) is equal to -4.
Answer 2
Answer:
f(7)=10-14=-4
Answer=-4
