Question

Найти f(5) если f(x)=-4X+15​

Answer 1

f(x) = - 4x + 15

f(5) = - 4 * 5 + 15 = - 20 + 15 = - 5

f(5) = - 5

Answer 2

To find the value of f(5) for the function f(x) = -4x + 15, we need to substitute x = 5 into the function and calculate the result.

f(5) = -4(5) + 15 = -20 + 15 = -5

Therefore, f(5) = -5.
