Given the relation y = 7x2 + 3, if the input is 4, what is the output? (4 points)

Answer:115
Step-by-step explanation:
I'm assuming that you meant: y = 7x² + 3 Remember! Inputs are always x values (unless stated otherwise). Meaning the problem says: x = 4 y = 7(4)² + 3 The square only applies to the 4. The 7 is not going to be squared! (To be exact it only applies to whatever the value of x is. 4² = 4·4 = 16 Remember: P arenthesisE xponentsM ultiplicationD ivisionA dditionS ubtraction Follow PEMDAS from left to right (or in the case above from top to bottom). 7·16 + 3 = ? 16·7 = 10·7 + 6·7 = 70 + 42 = 112 (All I did to multiply was break it up into parts. If it confuses you don't worry about it, and just multiply it out like normal or use a calculator if you are allowed to) 112 + 3 = ? Our output is: 115!
