Given that f(x) = 2x2 – 3, find f(2)
Online "^" is used to indicate and exponent, e.g., x^2 = x squared.
f(x) = 2x^2 – 3 = 2*2*2 - 3 = ?
Thank you
To find f(2), we need to substitute x = 2 into the function f(x) = 2x^2 - 3 and evaluate it.
Substitute x = 2 into the function:
f(2) = 2(2)^2 - 3
Evaluate the expression within the brackets:
f(2) = 2(4) - 3
Multiply 2 by 4:
f(2) = 8 - 3
Subtract 3 from 8:
f(2) = 5
Therefore, f(2) = 5.
