decide whether the function is linear. then evaluate the function for the given value of x. f(x)=x-11:f(4)
You can do this on a calculator.
for y put x-11 and see if its linear.
To evaluate just plug 4 for x so it would read f(4)=4-11=-7
Is there a subject called mumford?
To decide whether a function is linear, we need to determine if it follows the form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.
In the given function, f(x) = x - 11, we can rewrite it as y = x - 11 to match the linear equation form.
Here, the coefficient of x is 1, and there is no constant term (y-intercept), as -11 is the only term that doesn't involve x. Therefore, the slope (m) is 1, and the y-intercept (b) is -11.
Since the function follows the linear equation form, we can conclude that it is linear.
To evaluate the function for a specific value of x, in this case, f(4), we substitute the value of x into the function.
f(4) = 4 - 11
= -7
Therefore, when x is 4, the function f(x) equals -7.
