If f (x) = StartRoot 4 x + 9 EndRoot + 2, which inequality can be used to find the domain of f(x)?

a.) StartRoot 4 x EndRoot greater-than-or-equal-to 0
b.) 4 x + 9 greater-than-or-equal-to 0
c.) 4 x greater-than-or-equal-to 0
d.) StartRoot 4 x + 9 EndRoot + 2 greater-than-or-equal-to 0

The answer is actually b. Just took this quiz :)

Step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
