If (x) = 3x^2 + 10, what is f(-7)

f(x) = -139

Step-by-step explanation:

f(x) = 3x^2 + 10    If f(-7)

f(-7)= 3 * -7^2 + 10

F(-7) = 3 * -49 + 10

f(-7) = -147 + 10

f(-7) = -139

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

the answer is 5/14.

hope this .
