Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11
Use a all called math w.a.y (remove the periods) trust me it helps with at least 75% of math problems
Answer:
A
Step-by-step explanation:
Slope intercept form is
y=mx+b
y is y
3x is mx
and
b is 2
Answer:
13
Step-by-step explanation:
4/87 is around 0.046
13+0.046=13.046
13.046 to the nearest half is 13
