Given h, left bracket, x, right bracket, equals, 2, x, plus, 4h(x)=2x+4, find h, left bracket, minus, 1, right bracketh(−1).
To find h(x) - 1, we substitute -1 for x in the equation:
h(x-1) = 2(x-1) + 4
Simplifying this expression:
h(x-1) = 2x - 2 + 4
= 2x + 2
Therefore, h(-1) = 2(-1) + 2 = -2 + 2 = 0
To find h(-1) in the equation h(x) = 2x + 4, we need to substitute -1 for x.
Substituting -1 for x, we have:
h(-1) = 2(-1) + 4
Simplifying the expression:
h(-1) = -2 + 4
h(-1) = 2
To find h(-1), we need to substitute -1 into the equation for x and solve for h.
The given equation is:
h(x) = 2x + 4
Substituting x = -1 into the equation, we have:
h(-1) = 2(-1) + 4
Simplifying the expression, we get:
h(-1) = -2 + 4
h(-1) = 2
Therefore, h(-1) equals 2.
