3)The value of y when x=-2 will be 12.5.
What is an exponential function?The exponential function is classified as a function that increases swiftly and whose value is always positive. using the exponent y = aˣ,, where an is a constant greater than 1, and a>1.
It is given that the graph shows an exponential relationship between x and y.
1)
The standard exponential function is,
y=baˣ
y=50×2ˣ
2)
When x= -1 the obtained value of y is,
y=50×2ˣ
y=50×2⁻¹
y=50/2
y=25
3)
When x= -2 the obtained value of y is,
y=50×2ˣ
y=50×2⁻²
y=50/4
y=12.5
Thus, the equation for this relationship is y=50×2ˣ,, where the values of y at x=-1 and x=-2 are 25 and 12.5, respectively.
