Let f(x)=2/5x^2-2. the function g(x) is a vertical stretch of f(x) by the factor 2. what is the equation of g(x)?

g(x) = (4/5)x^2 - 2

Step-by-step explanation:

Start with the given f(x)=2/5x^2-2 and multiply (2/5)x^2 by 2, obtaining

g(x) = 2(2/5)x^2 - 2, or

g(x) = (4/5)x^2 - 2

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
