Tell whether the function is linear. Then evaluate the function for the given value of x.
3.) f(x)= x^2 + x-2 ; f(1)
Help please!!!
if it has x^2 in it it is certainly NOT linear !!!
f(1) = 1^2 + 1 - 2
To determine whether a function is linear, we need to check if it satisfies the properties of a linear function, which means it should have a constant rate of change.
In this case, the function given is f(x) = x^2 + x - 2.
To evaluate the function for a given value of x, substitute that value into the function and simplify.
For f(1):
f(1) = (1)^2 + (1) - 2
= 1 + 1 - 2
= 0
Therefore, f(1) = 0.
Now, let's check if f(x) is linear. For a function to be linear, the highest power of x should be 1, and the coefficient of x^1 should be constant. In this case, the highest power of x is x^2, which is not equal to 1. Therefore, the function f(x) = x^2 + x - 2 is not linear.
