Which of the following functions is graphed above?
a.
f(x) = 4log(x + 4)
b.
f(x) = -4log(x + 4)
c.
f(x) = 4log(-x - 4)
d.
f(x) = -4log(-x + 4)

The answer is D ⇒ -4log(-x + 4)

Step-by-step explanation:

From the graph we chose the point of x-intercept (3 , 0)

∵ f(x) = -4log(-x + 4)

∴f(3) = -4log(-3 + 4) = -4log(1)

∵ log(1) = 0

∴f(3) = 0

If x = 0

∴ f(0) = -4log(0 + 4) = -4log4 = -2.40 ⇒ same value on the graph

∴ The answer is (D)

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
