Find the Range
f(x) = -8x^2 - 10x + 7
*** "^" is exponent
The function has a maximum value at
x = -5/8. At that point, f(x) = -25/8 + 50/8 + 7 = 10 1/8
There is no lower limit to the function's value.
The range is -infinity to + 10 1/8
f(x) = -8x^2 - 10x + 7
*** "^" is exponent
x = -5/8. At that point, f(x) = -25/8 + 50/8 + 7 = 10 1/8
There is no lower limit to the function's value.
The range is -infinity to + 10 1/8
