A. Find the y-intercept, the equation of the axis of symmetry, and the x-coordinate of 2 Complete parts a-c for each quadratic function.
the vertex.
b. Make a table of values that includes the vertex.
c. Use this information to graph the function.
1. f(x) = 3x2
2. f(x) = – 6x²
3. f(x) = x2 - 4x
4. f(x) = – x2 – 3x + 4
5. f(x) = 4x2 - 6x - 3
6. f(x) = 2x2 – 8x + 5

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
