Let f(x)=8xf(x)=8x .
what function represents a transformation of f(x)f(x) by a vertical stretch with factor 2?
g(x)=2⋅8xg(x)=2·8x
g(x)=12⋅8xg(x)=12·8x
g(x)=812xg(x)=812x
g(x)=82x

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
