What is the equation of the following graph?

here we have graph which is the shape of parabola and a staright passing through y .

we know that general equal of parabola lies x axis

y=x^2

and the equation of straight line y=5

it means y=mx+b

where it is a straight line it does not have slope so m=0 x intercept is also 0 and y intercept is 5 .

if we plug these equation in straight line equation we get y=5

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
