can someone help me please?
To find the value of the function f for a specific value of x you substitute that value for x in the expression that defines the function:
In this case:
f(x) = 5*(x^2) - 2*x
So:
f(0) = 5*(0^2) - 2*0
= 0 - 0 = 0
f(-1) = 5*(-1)^2 - 2*(-1)
= 5*1 + 2
= 5 + 2 = 7
What then is f(2)?
