Answer:
A = 9, B = 5, C = 3
the parabola opens upwards
y-intercept = 3
Step-by-step explanation:
Since the equation is f(x)=9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, <u>ax^2+bx+c</u>. The numbers correspond with each letter in the skeletal equation.
To determine whether the parabola opens up or down, you can simply look at the a value. If <u>x > 0</u>, the the parabola will <u>open upwards</u>, whereas if <u>x < 0</u>, the parabola will <u>open downwards</u>.
To determine <u>y-intercept</u>, just plug in the value of 0 into x and solve for y.

Answer:
11·11^4
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a = a^1
(a^b)/(a^c) = a^(b-c)
a^0 = 1 . . . . for any 'a' not 0

The given expression is ...
(11^8)/(11^3) = 11^(8-3) = 11^5
The offered choices are ...
(11^7)/(11^7) = 11^(7-7) = 11^0 = 1
11·11^4 = (11^1)(11^4) = 11^(1+4) = 11^5 . . . . matches the given expression
(11^0)/(11^5) = 11^(0-5) = 11^-5
11^0 = 1
