If h(x)=(fog)(x) and h(x) = sqrt x+5, find g(x) if f(x) = sqrtx+2
Katen [24]

Answer: The value of g(x) is x+3.

Step-by-step explanation:

Since we have given that

h(x)=f\circ g(x)

Here,

h(x)=\sqrt{x+5}\\\\and\\\\f(x)=\sqrt{x+2}

We need to find the value of g(x):

f(x)=\sqrt{x+2}\\\\f(g(x))=\sqrt{g(x)+2}\\\\h(x)=\sqrt{g(x)+2}\\\\\sqrt{x+5}=\sqrt{g(x)+2}\\\\x+5=g(x)+2\\\\g(x)=x+5-2=x+3

Hence, the value of g(x) is x+3.

Choose the graph below that has an undefined slope.
Ronch [10]

Answer:

The correct option is A.

Step-by-step explanation:

The first line passing through the points (-6,2) and (-6,0).

The slope of a line is

m=\frac{y_2-y_1}{x_2-x_1}

The slope of first line is

m_1=\frac{0-2}{-6-(-6)}=\infty

The second line passing through the points (0,-4) and (-1,1). The slope of second line is

m_2=\frac{1-(-4)}{-1-0}=-5

The third line passing through the points (0,-6) and (2,-6). The slope of third line is

m_3=\frac{-6-(-6)}{2-0}=0

The fourth line passing through the points (0,6) and (-3,-7). The slope of fourth line is


m_4=\frac{-7-6}{-3-0}=\frac{13}{3}

Since the slope of a vertical line is infinity, Therefore option A is correct.
