User: Simplify the expression 5/8+ 7

User: f(x)=-6x-1 and g(x)=4x^2

Weegy: Consider the equations: f(x)=-6x-1 and g(x)=4x^2 Answer is: (fg)(x) (a)-6x-1+4x^2

User: Select the x-coordinate of the vertex of the parabola defined by the function f(x) = -3x2 + 7x + 1.

Weegy: The x-coordinate of the vertex of the parabola defined by the function f(x) = -5x^2 + 7x + 7 is -b/2a = 7/10

User: Select the x-coordinate of the vertex of the parabola defined by the function f(x) = -3x2 + 7x + 1.

Weegy: The x-coordinate of the vertex of the parabola defined by the function f(x) = -5x^2 + 7x + 7 is -b/2a = 7/10

User: Determine the equation of g(x) that results from translating the function f(x) = x2 + 1 upward 7 units.

Weegy: The equation of g(x) that results from translating the function f(x) = x^2 - 7 upward 11 units is g(x) = x^2 + 4.

User: Determine the equation of g(x) that results from translating the function f(x) = (x + 10)2 to the right 13 units. g(x) = (x - 3)2 g(x) = (x + 23)2 g(x) = (x + 10)2 - 13 g(x) = (x + 10)2 + 13

User: Select the approximate values of x that are solutions to f(x) = 0, where f(x) = -4x2 + 9x + 3.

The equation of g(x) that results from translating the function f(x) = x^2 + 1 upward 7 units is f(x) = x^2 + 8

f(x) = -4x^2 + 9x + 3 = 0
a = -4, b = 9, c = 3
b^2 - 4ac = 9^2 - 4(-4)(3) = 129
x = (-9 + sqrt129)/-8 = (9 - sqrt 129)/8 = - 0.29
or x = (-9 - sqrt129)/-8 = (9 + sqrt 129)/8 = 2.5
