Ответ:
f(-2) = -12
Step-by-step explanation:
f(x) = 2 • 3x.
Let x = -2
f(-2) = 2* 3(-2)
= -12
Ответ:
f(-2)=-12
Step-by-step explanation:
This question asks us to find f(-2). This means we need to find out what f(x), or y is, when x is equal to -2.
f(x)=2*3x
Therefore, we can substitute -2 in for every x.
f(-2)=2*3(-2)
Solve according to PEMDAS (Parentheses, Exponents, Multiplication, Division , Addition, Subtraction)
Multiply 3 and -2 first
f(-2)=2*-6
Multiply 2 and -6
f(-2)= -12
