liana started to evaluate the function f(x) = 2×2 – 3x + 7 for the input value 2.f(x) = 2(2)2 – 3(2) + 7= 2(4) – 3(2) + 7
To evaluate the function f(x) = 2x^2 – 3x + 7 for the input value x = 2, you need to substitute the value 2 in place of x and perform the necessary calculations
To evaluate the function f(x) = 2x^2 – 3x + 7 for the input value x = 2, you need to substitute the value 2 in place of x and perform the necessary calculations.
Starting with the given function:
f(x) = 2x^2 – 3x + 7
Substituting x = 2:
f(2) = 2(2)^2 – 3(2) + 7
Simplifying the equation within the parentheses first:
f(2) = 2(4) – 3(2) + 7
Next, perform the multiplications:
f(2) = 8 – 6 + 7
Now, solve the additions and subtractions:
f(2) = 15
Therefore, when the input value x is equal to 2, the result of the function f(x) = 2x^2 – 3x + 7 is 15.
It is important to note that the original equation can be evaluated for any value of x by following the same steps, substituting the value of x into the equation, simplifying, and performing the necessary arithmetic.
