Question

Find the exponential function that passes through
(0,-10) , (4,-160)

solve with steps please .-.

Answer 1

Answer: y=-(nth(151)^x)-9

Step-by-step explanation: put y=-(a^x)+c

when x=0 y=-10

-(a^0)-c=-10 => -1+c=-10 => c=-9

when x=4 y=-160

-(a^4)-9=-160 => -(a^4)=-151 => a^4=151 => a=nth(151)
