Evaluate the expression 3f(2) - 3g(-4) for the given functions f and g?
f (x) = 5x - 2
g(x) = 5 - x^2
really? just plug and chug
3(5*2-2) - 3(5 - (-4)^2) = ____
That made me laugh lol sorry dude sometimes one of the boys needs help lol
To evaluate the expression 3f(2) - 3g(-4) for the given functions f and g, we need to substitute the given values of x into the respective functions and perform the necessary calculations.
First, let's substitute x = 2 into the function f(x) = 5x - 2:
f(2) = 5(2) - 2
= 10 - 2
= 8
Next, let's substitute x = -4 into the function g(x) = 5 - x^2:
g(-4) = 5 - (-4)^2
= 5 - 16
= -11
Now, let's substitute these values into the original expression and perform the calculations:
3f(2) - 3g(-4) = 3(8) - 3(-11)
= 24 + 33
= 57
Therefore, the evaluation of the expression 3f(2) - 3g(-4) for the given functions f and g is 57.
