(0,-4),(1,0),(2,2) find a quadratic function in standard form for each set of points.
Sphinxa [80]
We are given the points
 <span>(0,-4),(1,0),(2,2)
The standard form a quadratic function (in terms of x) is
y = Ax2 + Bx + C
Subsitute the points
-4 = 0 + 0 + C
C = -4

0 = A + B - 4

2 = 4A + 2B - 4

Solve for A and B
A = -1
B = 5

The function is
y = -x2 + 5x - 4</span>

If f(x) = 2x + 1 and g(x) = x2 + 5,<br> what is g(f(2))?
Amiraneli [1.4K]

Answer:

30 if that is an x^{2} in g(x)

Step-by-step explanation:

f(2) = 2x + 1

      = 2(2) + 1

      = 4 + 1

f(2) = 5      

g(5) = x^{2} + 5

      = 5^{2} + 5

      = 25 + 5

g(5) = 30
