[tex]a =7000[/tex]
[tex]b = 0.4[/tex]
Step by step:
Firstly, we should substitute the points where x is equal to 0 so that we can obtain the a value
[tex]7000 = a {b}^{0} [/tex]
And because anything to the power of 0 is 1
[tex]7000 \: = a \times 1 = a[/tex]
Now that we have the value for a, we can substitute it into the 2nd equation to find b
[tex]1120 = 7000 {b}^{2} [/tex]
Finally, we rearrange to make b the subject
[tex] \frac{1120}{7000} = {b}^{2} \\ \sqrt{ \frac{1120}{7000} } = b \\ b = 0.4[/tex]
