Question

For the function f(x, y) = 2x + 3y - 7, please find the value of f(4,-2)

Answer 1

2x + 3y - 7 = -5

Explanation:

You just substitute the values in. X would be 4, and Y would be -2

2(4) + 3(-2) - 7

Simplify

8 + -6 - 7

8 + -13 = -5

Answer 2

Explanation:

f(x, y) = 2x + 3y - 7

f(4, -2) = 2(4) + 3(-2) - 7

f(4, -2) = 8 - 6 - 7

f(4, -2) = -5
