The function h is defined by h(x) = 3x − 7. What is the value of h(−2)?
A) −13
B) −10
C) 10
D) 13
Answer
We’re given the function: h(x) = 3x – 7
And we’re told to solve h(-2), which means x=-2
To find h(-2), we substitute (-2) everywhere we see (x).
Original equation: h(x) = 3x – 7
With substitution: h(-2) = 3(-2) – 7
Solving this gives us:
h(-2) = – 6 – 7
Remember: 3(-2) means we multiply 3 with -2, which gives us -6.
Further solving this:
h(-2) = -13
The correct answer is A
