Answer:
Step-by-step explanation:
<u>Dilation is applied by the rule:</u>
- (x, y) → (kx, ky), where k is the scale factor
<u>We have</u>
- (x, y) = (-2, 3) and (kx, ky) = (-8, 12)
<u>Substitute and solve for k</u>
- -8 = -2k and 12 = 3k ⇒ k = 4
<u>So the rule is</u>
Answer:
B
Step-by-step explanation:
It's b my correct answer is b
This is [ (f(2) - f(-2) ] / ( 2 - (-2)
= 1/16 - 16 / 4
= -255/64
= -3 63/64
Answer:
C
