Answer:
d(-3) = -5
Step-by-step explanation:
To find d(-3), plug in -3 wherever there is an x in d(x).
d(x) = 2x + 1
d(-3) = 2(-3) + 1
d(-3) = -6 + 1
d(-3) = -5
Answer:
d(-3) = -5
Step-by-step explanation:
To find the answer substitute x for -3
This means the equation will now look like
d(-3) = 2(-3) + 1
d(-3) = -6 + 1
d(-3) = -5
